Search for new physics using single-lepton events with high multiplicities of jets and b jets in proton-proton collisions at $$ \sqrt{s}=13 $$ TeV

<jats:title> A <jats:sc>bstract</jats:sc> </jats:title> <jats:p> This paper presents a search for beyond the standard model physics using single-lepton events with a high multiplicity of jets, including those identified as bottom quark jets, without a requirement on missing transverse momentum. The analysis is based on proton-proton collision data collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb <jats:sup> <jats:italic>−</jats:italic> 1 </jats:sup> . This search is sensitive to <jats:italic>R</jats:italic> -parity violating supersymmetry models, where supersymmetric particles can decay into standard-model particles through interactions that violate baryon number conservation. In particular, the signal model considered is gluino pair production, where each gluino decays into top, bottom, and strange quarks. The sum of large-radius jet masses is used to distinguish the signal from background, as it effectively captures the features of high jet multiplicity and high interaction energy. No significant excess of data over the background predictions is observed. Gluinos in this model have been excluded for masses below 1890 GeV at 95% confidence level. </jats:p>

Machine Learning on Heterogeneous, Edge, and Quantum Hardware for Particle Physics

, PRX Intelligence, Vol: 1

<jats:p>The next generation of particle physics experiments will face an era of challenges in data acquisition, due to unprecedented data rates and volumes along with extreme environments and operational constraints. Harnessing these data for scientific discovery demands real-time inference and decision-making, intelligent data reduction, and efficient processing architectures beyond current capabilities. Crucial to the success of this experimental paradigm are several emerging technologies, such as artificial intelligence and machine learning, silicon microelectronics, and the advent of quantum algorithms and processing. Their intersection includes areas of research such as low-power and low-latency devices for edge computing, heterogeneous accelerator systems, reconfigurable hardware, codesign and synthesis strategies, readout for cryogenic or high-radiation environments, and analog computing. This white paper presents a community-driven vision to identify and prioritize research and development opportunities in hardware-based ML systems and corresponding physics applications, contributing toward a successful transition to the data frontier of fundamental science.</jats:p>

Observation of Nuclear Suppression in Coherent ϒ(1S) Photoproduction off Heavy Nuclei at the LHC.

, Phys Rev Lett, Vol: 137

The first measurement of coherent ϒ(1S) meson photoproduction off heavy nuclei is performed using ultraperipheral lead-lead collisions collected by the CMS experiment at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The nuclear gluonic structure is probed at a nucleon momentum fraction of order x∼10^{-3}, determined by the kinematics of the process. Owing to the large ϒ(1S) mass, the measurement reaches the highest scale accessible so far through coherent vector-meson photoproduction, μ^{2}=22.4 GeV^{2}, where nonlinear quantum chromodynamics effects are expected to be minimal. In the ϒ(1S) rapidity range |y|<1, the ratio of the measured photoproduction cross section to a baseline model prediction that neglects nuclear effects is S_{ϒ(1S)}=0.25±0.06(stat)±0.02(syst), thereby demonstrating nuclear suppression in this process. Expressed in terms of a nuclear gluon suppression factor, the result yields R_{g}^{Pb}(x≈10^{-3},μ^{2}=22.4 GeV^{2})=0.55±0.12(stat)±0.02(syst). The measured S_{ϒ(1S)} is only slightly larger than the values previously reported for coherent ϕ photoproduction, despite the probed μ^{2} differing by approximately 2 orders of magnitude.

Observation of ϒ(1S)+Z Associated Production and Measurement of the Effective Double-Parton Scattering Cross Section in Proton-Proton Collisions at sqrt[s]=13 TeV.

, Phys Rev Lett, Vol: 137

The observation of the associated production of an ϒ(1S) meson with a Z boson and a measurement of the ratio of its fiducial cross section to the fiducial cross section of the Z boson are presented. Both the ϒ(1S) meson and the Z boson are identified via decays into a pair of opposite-sign muons. The analysis is based on proton-proton (pp) collision data at sqrt[s]=13 TeV collected with the CMS detector in 2016-2018 and corresponding to an integrated luminosity of 138 fb^{-1}. Using the production of the Z boson decaying into four muons as a normalization channel, the ratio of the fiducial cross sections σ[pp→Z+ϒ(1S)]B(Z→μ^{+}μ^{-})B[ϒ(1S)→μ^{+}μ^{-}] to σ(pp→Z)B(Z→4μ) is measured to be R_{Z+ϒ(1S)}=[21.1±5.5(stat)±0.6(syst)]×10^{-3}, where stat and syst denote the statistical and systematic uncertainties, respectively. The result is used to extract the effective double-parton scattering cross section σ_{eff}=13.0_{-3.4}^{+7.7} mb.

Measurement of the Ratio of Branching Fractions B(B_{c}^{+}→J/ψτ^{+}ν_{τ})/B(B_{c}^{+}→J/ψμ^{+}ν_{μ}).

, Phys Rev Lett, Vol: 137

A measurement of the ratio of semileptonic branching fractions R(J/ψ), defined as R(J/ψ)≡B(B_{c}^{+}→J/ψτ^{+}ν_{τ})/B(B_{c}^{+}→J/ψμ^{+}ν_{μ}), is reported using a sample of proton-proton collision data corresponding to an integrated luminosity of 5.4 fb^{-1} recorded by the LHCb experiment in 2016-2018 at a center-of-mass energy of 13 TeV. The measured value is found to be R(J/ψ)=0.51±0.12(stat)±0.08(syst), which is within 1.8 standard deviations of the predictions from the standard model assuming lepton flavor universality.

Search for a new heavy scalar resonance decaying to a pair of Z bosons in the four-lepton final state in proton-proton collisions at s=13 TeV

, Journal of High Energy Physics, Vol: 2026

A search for a new heavy scalar resonance decaying to two Z bosons, each subsequently decaying to a pair of electrons or muons, is presented. The results are based on a proton-proton collision data set collected by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb−1. The search is performed over a wide range of resonance masses from 130 GeV to 3 TeV, considering both narrow- and broad-width scenarios, and considering the gluon fusion and vector boson fusion production processes. For the broad-width scenario, the interference between the new resonance, the 125 GeV Higgs boson production, and the continuum background is taken into account. No significant excess with respect to the standard model background expectation is observed in the examined phase space. Upper limits at the 95% confidence level are set on the product of the heavy scalar resonance production cross section and the branching fraction for its decay into two Z bosons. The exclusion limits range from 0.05–0.1 pb in the low-mass region to 0.005 pb in the high-mass region.

Particle transformers for identifying Lorentz-boosted Higgs bosons decaying to a pair of W bosons

, Journal of High Energy Physics, Vol: 2026

A novel deep neural network classifier, a “particle transformer” (ParT), is introduced for the identification of highly Lorentz-boosted resonances reconstructed as single, multipronged jets in measurements and searches performed by the CMS Collaboration at the CERN LHC. Based on a self-attention mechanism that allows the model to weigh the importance of different particles, ParT is trained on a wide variety of topologies, notably demonstrating strong performance for the first time on jets originating from boosted Higgs boson decays to W bosons. The ParT algorithm achieves a tagging efficiency of more than 50% for such jets at a background efficiency of 1%, while maintaining decorrelation from the jet mass. A calibration is performed in proton-proton collision data collected by CMS at a center-of-mass energy of 13 TeV, with a data set corresponding to a total luminosity of 138 fb−1. Data-to-simulation selection efficiency scale factors are measured to be in the 0.9–1.0 range, with relative uncertainties between 7 and 23%. The tagging capability of ParT enhances the sensitivity of standard model measurements and searches for beyond-the-standard-model resonances decaying to hadronic diboson systems.

Search for the Nonresonant Production of a Pair of Additional Higgs Bosons in the Type-X Two-Higgs-Doublet Model in Proton-Proton Collisions at sqrt[s]=13 TeV.

, Phys Rev Lett, Vol: 137

A search is presented for the production of two additional Higgs bosons from an off-shell Z boson, where both additional particles decay to τ lepton pairs. The search is performed with a data sample collected with the CMS detector from proton-proton collisions at the LHC at sqrt[s]=13 TeV, corresponding to an integrated luminosity of 138 fb^{-1}. No deviation from the standard model background is observed. Exclusion limits are set on the type-X two-Higgs-doublet model alignment scenario. These results exclude previously unexplored regions of parameter space and provide constraints complementary to those from earlier searches.

Search for Electroweakinos in Compressed-Spectrum Scenarios with Low-Momentum Isolated Tracks in Proton-Proton Collisions at sqrt[s]=13 TeV.

, Phys Rev Lett, Vol: 137

A search for supersymmetric electroweakinos is performed using events with a low-momentum (soft) isolated track and large missing transverse momentum, targeting nearly mass-degenerate higgsinolike charginos and neutralinos. For mass splittings of 0.3-1 GeV, the chargino decays to the lightest neutralino and a low-momentum pion, which can produce a soft, potentially displaced track. A parametrized neural network separates signal from background using kinematic and impact parameter information. The analysis uses 138 fb^{-1} of proton-proton collision data at a center-of-mass energy of 13 TeV recorded with the CMS detector. No significant excess above the standard model expectation is observed. At 95% confidence level, the considered higgsino model is excluded for mass splittings in the range 0.28-1.15 GeV and for chargino masses up to 185 GeV, setting stringent constraints on natural supersymmetry scenarios.

Combination of ATLAS and CMS Searches for Higgs Boson Pair Production at sqrt[s]=13 TeV.

, Phys Rev Lett, Vol: 137

This Letter presents a combination of searches for Higgs boson pair (HH) production performed by the ATLAS and CMS Collaborations using proton-proton collision datasets recorded at sqrt[s]=13 TeV during the Large Hadron Collider Run 2, corresponding to integrated luminosities ranging between 126 and 140 fb^{-1}. The upper limit at the 95% confidence level on the total HH signal strength, defined as the ratio of the measured cross section to the standard model (SM) prediction, corresponds to 2.5, with an expected value of 1.7 (2.8) assuming the absence (presence) of the SM HH signal. The strength of the HH signal is measured to be 0.8_{-0.7}^{+0.9} relative to the SM prediction. The observed significance is found to be 1.1 standard deviations whereas 1.3 are expected for the SM HH signal. Constraints are set on the Higgs boson trilinear self-coupling and on the couplings of two Higgs bosons to two vector bosons, both normalized to the SM predictions and denoted as κ_{λ} and κ_{2V}, respectively. The observed individual constraints at the 95% confidence level are -0.71<κ_{λ}<6.1 and 0.73<κ_{2V}<1.3, while the expected constraints assuming the presence of the SM HH signal are -1.3<κ_{λ}<6.7 and 0.66<κ_{2V}<1.4.

<jats:p> This work presents single-differential electron-neutrino charged-current cross sections on argon measured using the MicroBooNE detector at the Fermi National Accelerator Laboratory. The analysis uses data recorded when the Neutrinos at the Main Injector beam was operating in both neutrino and antineutrino modes, with exposures of <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:mn>2</a:mn> <a:mo>×</a:mo> <a:msup> <a:mn>10</a:mn> <a:mn>20</a:mn> </a:msup> </a:math> and <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"> <c:mn>5</c:mn> <c:mo>×</c:mo> <c:msup> <c:mn>10</c:mn> <c:mn>20</c:mn> </c:msup> </c:math> protons on target, respectively. A selection algorithm targeting electron-neutrino charged-current interactions with at least one proton, one electron, and no pions in the final topology is used to measure differential cross sections as a function of outgoing electron energy, total visible energy, and the cosine of the opening angle between the electron and the most energetic proton. The interaction rate as a function of proton multiplicity is also reported.

Constraints on Solar Reflected Dark Matter from XENON1T and XENONnT Data.

, Phys Rev Lett, Vol: 137

We report on a search for sub-GeV dark matter upscattered via the solar reflection mechanism in the heavy mediator scenario. Under the standard halo model, keV-MeV dark matter produces nuclear recoils with energies below the detection threshold of liquid xenon time projection chambers. We enhance sensitivity to low-mass dark matter (DM) by considering dark matter-electron scattering, employing dedicated event selections to reduce the detection threshold and exploiting the additional kinetic energy imparted to the dark matter particle by solar upscattering. Using XENON1T ionization-only and XENONnT low-energy electronic recoil datasets, we exclude previously unconstrained DM-electron scattering cross section for masses between 4.6 and 20 keV/c^{2} and between 0.2 and 2 MeV/c^{2}, reaching a minimum of 3.41×10^{-39} cm^{2} for a mass of 0.3 MeV/c^{2} at 90% confidence level.

Precision Measurement of the Muon Charge Asymmetry from W-Boson Decays in pp Collisions at sqrt[s]=13 TeV in the Forward Region.

, Phys Rev Lett, Vol: 137

A precision measurement of the muon charge asymmetry from W-boson decays in proton-proton collisions at sqrt[s]=13 TeV is presented. The analysis utilizes data corresponding to an integrated luminosity of 5.1 fb^{-1}, recorded by the LHCb detector during 2016, 2017, and 2018. The asymmetry is measured for muons with transverse momentum between 25 and 55 GeV and pseudorapidity between 2.0 and 4.5. This result represents the most precise determination of the muon charge asymmetry in the forward region to date, exhibiting excellent agreement with next-to-next-to-leading-order predictions in perturbative quantum chromodynamics. The measured asymmetries are corrected for experimental efficiencies, resolution, and final-state photon radiation.

Search for Associated Production of a Higgs Boson and Two Vector Bosons via Vector-Boson Scattering at sqrt[s]=13 TeV.

, Phys Rev Lett, Vol: 137

A search for Higgs boson (H) production in association with two vector bosons (V=W, Z) via vector-boson scattering (VBS) is presented using proton-proton collision data collected at sqrt[s]=13 TeV by the CMS experiment, corresponding to an integrated luminosity of 138 fb^{-1}. Events containing two forward jets consistent with VBS, a large-radius jet from the decay of a boosted H to a pair of b quarks, and zero, one, or two charged leptons coming from V decays are selected. The process is excluded at 95% confidence level for observed (expected) values of the VVHH coupling modifier κ_{2V} outside the interval 0.40<κ_{2V}<1.60 (0.34<κ_{2V}<1.66), assuming standard model values for all other couplings, thus establishing a novel probe of the VVHH interaction. Constraints are also set on the individual κ_{2W} and κ_{2Z} coupling modifiers and on the allowed region in the κ_{2W}-κ_{2Z} plane.

Highly boosted dielectron identification in proton-proton collisions at √s = 13 TeV

, Physical Review D, Vol: 114, ISSN: 2470-0010

A new technique is developed to identify dielectrons (e+e−) with Lorentz boost γ<inf>L</inf>?> 20 that produce one single merged cluster in the electromagnetic calorimeter of the CMS detector. The identification uses two multivariate models: one for the case where both electron tracks are reconstructed, and another where only one of the tracks is reconstructed. The efficiency is determined using proton-proton collision data collected at a center-of-mass energy of 13 TeV. Boosted J=ψ mesons decaying into e+e− pairs are used to estimate the efficiency of the model with two tracks, yielding an overall efficiency of 80%. The Z → μþμ−γ events, where the photon converts into a collimated dielectron, are used for the model with a single track, yielding an efficiency of about 60%. A dedicated energy correction for dielectron candidates is also developed using B± → J=ψK± → e+e−K± data.

Search for New Physics via Low-Energy Electron Recoils with a 4.2 Tonne-Year Exposure from the LZ Experiment.

, Phys Rev Lett, Vol: 137

We report results from searches for new physics models through electron recoils using data collected by the LUX-ZEPLIN experiment during its first two science runs, with a total exposure of 4.2 tonne-years. The observed data are consistent with a background-only hypothesis. Constraints are derived for electromagnetic interactions of solar neutrinos, solar axionlike particles (ALPs), mirror dark matter, and the absorption of bosonic dark matter candidates. The inverse Primakoff process for ^{57}Fe deexcitation solar ALPs is considered for the first time. These results represent the most stringent constraints to date on keV-scale Primakoff and ^{57}Fe solar ALPs, bosonic dark matter, mirror dark matter, and neutrino millicharge, while remaining competitive for the other signal models investigated.

System-size dependence of charged-particle suppression in ultrarelativistic nucleus-nucleus collisions

, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 880, ISSN: 0370-2693

High-energy partons lose energy while propagating through the hot, strongly interacting medium produced in ultrarelativistic nucleus-nucleus collisions, leading to a suppression of particle production at high transverse momentum (p <inf>T</inf>). The dependence of this energy loss on the size of the colliding nuclear system has yet to be firmly established experimentally. This Letter presents a systematic study of charged-particle suppression across four different nucleus-nucleus collision systems using nuclear modification factors (R <inf>AA</inf>) measured by the CMS Collaboration at the CERN LHC. Previous CMS measurements of R <inf>AA</inf> in oxygen-oxygen, xenon-xenon, and lead-lead collisions are recast with identical p <inf>T</inf> intervals and are complemented by the first measurement of the charged-particle R <inf>AA</inf> in neon-neon collisions at [b]s<inf>NN</inf>=5.36TeV. The neon-neon data correspond to an integrated luminosity of 0.76nb−1. The R <inf>AA</inf> in all collision systems examined show similar qualitative trends as a function of p <inf>T</inf>, but have a magnitude which is ordered with the nucleon number A . The R <inf>AA</inf> feature a downward slope at low p <inf>T</inf>, a local minimum at around 5–7GeV, and an upward slope with increasing p <inf>T</inf>. The R <inf>AA</inf> are also compared in terms of A 1/3, which is proportional to the nuclear radius. Models including only initial-state nuclear effects fail to reproduce the observed trends, whereas energy loss models reproduce the trends in the region p<inf>T</inf>'9.6GeV.

A high-flux source of cold strontium with a loading rate of 4×1010 atoms/s for open release

, Avs Quantum Science, Vol: 8

We present a high-flux source of cold strontium atoms based on a two-dimensional magneto-optical trap (2D MOT) and a Zeeman slower. We use the source to load a 3D MOT in a separate science chamber, observing a loading rate of 4 × 1010 atoms / s—to our knowledge, the highest reported loading flux for strontium. To characterize the vacuum pressure in the science chamber, we load the atoms into a magnetic trap and measure a lifetime of between 8 and 24 s, depending on the oven temperature. Finally, we characterize the atom flux and velocity distributions from the oven and from the 2D MOT source, finding reasonable agreement with models in the free molecular flow regime. Our results show that it is possible to readily produce a cold strontium flux at comparable levels to those of alkali species, at oven temperatures compatible with long-term operation, and at vacuum pressures suitable for state-of-the-art quantum experiments. We make our design available at no cost to benefit researchers in the quantum community.

Search for τ−→ μ−μ+μ− decays at the LHCb experiment with Run 2 data

, Journal of High Energy Physics, Vol: 2026

A search for the lepton-flavour-violating decay τ− → μ−μ+μ− is carried out using data collected by the LHCb experiment between 2016 and 2018 in proton-proton collisions at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb−1. An upper limit of 1.9 (2.3) × 10−8 is set at the 90% (95%) confidence level on the branching fraction of the decay.

SND@LHC upgrade for the high-luminosity LHC: physics reach and installation scenarios

, European Physical Journal C, Vol: 86, ISSN: 1434-6044

The SND@LHC experiment is currently taking data at the Large Hadron Collider (LHC), exploring the unique forward region at pseudorapidities 7.2<η<8.4. Its physics programme covers neutrinos originating from heavy-flavour decays and feebly interacting particles produced in proton–proton collisions. Building upon the successful operation of the present detector, this paper presents the physics reach of the approved SND@LHC upgrade for Run 4 of the LHC, and compares it with an alternative installation scenario. Lowering the detector by approximately 40 cm and shifting it horizontally by about 30 cm, while keeping it off-axis, increases the total neutrino interaction rate by a factor of five. The paper describes the design of the upgraded detector and compares the physics performance in both installation scenarios.

Simultaneous measurements of N-subjettiness observables in jets from gluons and light-flavour quarks, and in decays of boosted W bosons and top quarks

, Journal of High Energy Physics, Vol: 2026

A simultaneous measurement of 25 substructure observables is presented using large-radius jets with high transverse momentum from proton-proton collisions at s=13 TeV. The measurement is carried out on dijet events and tt¯ events enriched in Lorentz-boosted W bosons and top quarks decaying hadronically. The three data samples consist of jets with one, two, or three prongs from the showering and hadronization of a gluon or light-flavour quark, two quarks, or three quarks, respectively. The data correspond to an integrated luminosity of 138 fb−1, recorded by the CMS experiment in 2016–2018. A detailed characterization of the jet substructure is provided using a 6-body basis of N-subjettiness observables that overconstrains the phase space of the resolved emissions in the jet. The measurements are unfolded to the level of stable particles, and an estimate of the particle-level correlations between observables is provided, ensuring that the results can be used to systematically assess and refine the modelling of radiation in jets.
