<jats:title> A <jats:sc>bstract</jats:sc> </jats:title> <jats:p> Event shape variables, constructed from the four-momenta of the final-state objects in an event, are sensitive to the predictions of quantum chromodynamics in multijet production. A measurement of five event shape variables is presented, using proton-proton collision data collected at a centre-of-mass energy of 13 TeV with the CMS detector during 2016–2018, corresponding to an integrated luminosity of 138 fb <jats:sup> <jats:italic>−</jats:italic> 1 </jats:sup> . The variables are evaluated using the charged particles inside jets. After correcting for detector effects, their distributions are compared with the predictions from several models for multijet production. Overall, there is general agreement between several theoretical predictions and the data with scope for improvement of our understanding of QCD at different energy scales. </jats:p>

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 $$ \sqrt{s}=13 $$ TeV

, Journal of High Energy Physics, Vol: 2026

<jats:title> A <jats:sc>bstract</jats:sc> </jats:title> <jats:p> 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 <jats:sup> <jats:italic>−</jats:italic> 1 </jats:sup> . 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. </jats:p>

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.

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.

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

, Physical Review Letters, Vol: 137, ISSN: 0031-9007

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/c2 and between 0.2 and 2 MeV/c2, reaching a minimum of 3.41×10-39 cm2 for a mass of 0.3 MeV/c2 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.

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.

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.

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.

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 a new heavy resonance decaying to a top quark and a neutral scalar boson in proton-proton collisions at s=13TeV

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

A first search at the LHC for a new heavy resonance decaying to a top quark and a neutral scalar boson ϕ in the fully hadronic final state is presented, where the ϕ boson is identified by its decay into a bottom quark-antiquark pair. The search is focused on final states in which the decay products of the highly Lorentz boosted top quark and ϕ boson are each reconstructed as a single, large-radius jet with distinct substructure. The analysis is performed using proton-proton collision data at a center-of-mass energy of 13TeV, corresponding to an integrated luminosity of 138fb−1, recorded with the CMS detector at the LHC in 2016–2018. The single production of a vector-like top quark, T′, is used as a benchmark model for the signal process. The results of this search are combined with those of a previous CMS search in which semileptonic decays of the top quark were used. No significant excess of data is observed with respect to the background prediction. For the case where the neutral scalar is a standard model Higgs boson and the T′ quark width is 5% of its mass, T′ quark masses between 0.85 and 1.3TeV are excluded at 95% confidence level and the most stringent limits to date are set for masses above 2TeV. For other ϕ boson masses, upper limits as low as 0.1fb are set on the product of the T′ quark production cross section and branching fraction for its decay to a top quark and a ϕ boson.

Transition-Edge Sensor Spectrometer for Precision Spectroscopy of Antiprotonic Atoms

, IEEE Transactions on Applied Superconductivity, Vol: 36, ISSN: 1051-8223

antiProtonic Atom X-ray (PAX) spectroscopy is an experiment that aims to test strong-field quantum electrodynamics (QED) effects by performing high-precision X-ray spectroscopy of antiprotonic atoms. PAX will use a low-energy antiproton beam provided by the Extra Low ENergy Antiproton (ELENA) ring at the European Organization for Nuclear Research (CERN) to create antiprotonic atoms. A superconducting transition-edge sensor (TES) spectrometer will be used to measure the energy of transitions between circular Rydberg states in these atoms. The energy range of interest for the experiment spans 50 keV to 250 keV, and the desired precision for measuring the centroids of the emission lines is 10^{-5}. The spectrometer for PAX is intended to have four 96-pixel TES arrays and will be read out with a microwave superconducting quantum interference device (SQUID) multiplexer. As a step toward building the full instrument, we built a scaled-down version of the spectrometer that was installed at the TEst Line for Machine And Antimatter eXperiments (TELMAX) facility at ELENA in April 2025. The purpose of this deployment was to make an observation of X-ray emission by antiprotonic atoms and to better understand the effect of the pionic charged particle background due to antiproton annihilation on the performance of the TES array. This pilot spectrometer had an array of 60 TES pixels in a compact adiabatic demagnetization refrigerator cryostat. The sensors were read out with a microwave SQUID multiplexer. Each pixel consisted of a molybdenum/gold bilayer TES with a coplanar gold “landing pad” for a bulk tin absorber that was attached by an epoxy joint. We discuss the design of the TES pixels, the microwave SQUID readout, and the cryogenic platform. Finally, we present calibration data obtained at TELMAX using radioactive sources to assess the performance of the spectrometer in the antiproton beam-off condition.

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.

Full event interpretation with machine-learning-based particle-flow reconstruction in the CMS detector

, The European Physical Journal C, Vol: 86

<jats:title>Abstract</jats:title> <jats:p> The particle-flow (PF) algorithm constructs a global description of each particle collision by producing a comprehensive list of final-state particles, and is central to event reconstruction in the CMS experiment at the CERN LHC. The existing PF implementation relies on physics-motivated heuristics and assumptions that can be replaced by machine-learning (ML) models trained directly on simulated data and naturally suited to modern graphics processing units (GPUs). A state-of-the-art ML-based PF (MLPF) reconstruction algorithm, implemented within the CMS software framework, is presented. The MLPF algorithm performs a learnable full-event reconstruction on GPUs, generalizes across detector conditions and collision energies, and replaces multiple modular reconstruction steps with a single unified model. Physics performance comparable to standard PF reconstruction is achieved in both simulation and data, with improved jet energy resolution and inference time. In simulated top quark-antiquark events under LHC Run-3 (2023–2024) conditions, the jet energy resolution improves by 10–20% for jets with transverse momentum between 30–100 GeV.

Probing the Solar ^{8}B Neutrino Fog with XENONnT.

, Phys Rev Lett, Vol: 137

We report a 3.3σ measurement of coherent elastic neutrino-nucleus scattering from solar ^{8}B neutrinos using a 6.77 t×yr exposure from the XENONnT experiment, inferring a solar ^{8}B neutrino flux of (5_{-2}^{+3})×10^{6} cm^{-2} s^{-1}, consistent with previous measurements. In the presence of the ^{8}B "neutrino fog," we find no evidence for light dark matter, and observe diminishing returns in sensitivity with increasing exposure. A 93% increase in exposure from the previous search improves the median sensitivity to the nucleon scattering cross section for a 5 GeV/c^{2} spin-independent weakly interacting massive particle by 10%. The dataset was also used to measure the weak mixing angle at ∼0.02 GeV/c momentum transfer and constrain physics beyond the Standard Model.

Evidence of ZZγ Production and Observation of 4ℓγ in Proton-Proton Collisions at sqrt[s]=13 TeV.

, Phys Rev Lett, Vol: 137

Evidence of the production of two Z bosons and a photon in proton-proton collisions is reported for the first time in CMS. The analysis uses data collected by the CMS experiment between 2016 and 2018 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb^{-1}. Evidence for the process pp→ZZγ→4ℓγ (ℓ=e, μ), with an observed (expected) significance of 3.7 (3.1) standard deviations in a fiducial region defined by p_{T}^{γ}>20 GeV, |η^{γ}|<2.4, ΔR(ℓ,γ)>0.5, m_{Z} between 60 and 120 GeV, and the invariant mass of either of the two Z bosons combined with the photon (m_{Z_{γ}}) larger than 100 GeV, is reported. The measured (predicted) fiducial cross section is 60_{-22}^{+27} ab (47.56±0.04 ab). Additionally, the inclusive production of pp→4ℓγ is studied by removing the m_{Z_{γ}} requirement to include final state radiation where one Z boson decays to 2ℓγ, yielding an observed (expected) significance of 5.0 (4.2) standard deviations and a measured (predicted) fiducial cross section of 156_{-35}^{+39} ab (99.97±0.09 ab).

Searches for Light Dark Matter and Evidence of Coherent Elastic Neutrino-Nucleus Scattering of Solar Neutrinos with the LUX-ZEPLIN (LZ) Experiment.

, Phys Rev Lett, Vol: 137

We present searches for light dark matter (DM) with masses 3-9 GeV/c^{2} in the presence of coherent elastic neutrino-nucleus scattering (CEνNS) from ^{8}B solar neutrinos with the LUX-ZEPLIN experiment. This analysis uses a 5.7 tonne-yr exposure with data collected between March 2023 and April 2025. In an energy range spanning 1-6 keV, we report no significant excess of events attributable to dark matter nuclear recoils, but we observe a significant signal from ^{8}B CEνNS interactions that is consistent with expectation. We set world-leading limits on spin-independent and spin-dependent-neutron DM-nucleon interactions for masses down to 5 GeV/c^{2}. In the no-dark-matter scenario, we observe a signal consistent with ^{8}B CEνNS events, corresponding to a 4.5σ statistical significance. This is the most significant evidence of ^{8}B CEνNS interactions and is enabled by robust background modeling and mitigation techniques. This demonstrates LZ's ability to detect rare signals at keV-scale energies.

Polarization Measurement of Λ_{c}^{+} and Λ[over ¯]_{c}^{-} Baryons in p-Ne Collisions at sqrt[s_{NN}]=68.6 GeV.

, Phys Rev Lett, Vol: 137

The first measurement of the polarization of charm baryons by the LHCb experiment recorded in fixed-target mode is presented. The polarization of Λ_{c} baryons is studied in collisions of protons, at an energy of 2.51 TeV, incident on a gaseous target of neon, at a nucleon-nucleon center-of-mass energy of 68.6 GeV. The world's first measurement of separate-charge polarizations for Λ_{c}^{+} and Λ[over ¯]_{c}^{-} baryons is performed, determining P_{Λ_{c}^{+}}=(24±9±2)%, P_{Λ[over ¯]_{c}^{-}}=(-8±12±3)%, where the first uncertainty is statistical and the second systematic. The polarization is also measured in intervals of baryon transverse momentum and the Feynman-x variable.
