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.

Search for Higgs bosons produced in association with a high-energy photon via vector-boson fusion and decaying to a pair of b-quarks in the ATLAS detector

, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 877, ISSN: 0370-2693

A search for Standard Model Higgs bosons produced in association with a high-energy photon and decaying to bb¯ is performed using 133 fb−1 of s=13 TeV pp collision data collected with the ATLAS detector at the Large Hadron Collider at CERN. The photon requirement reduces the multijet background, and the H→bb¯ decay is the dominant decay mode. Event selection requirements target events produced by vector-boson fusion, the dominant production mode in this channel. Several improvements enhance the search sensitivity compared to previous measurements. These improvements include better background modelling and characterization, the use of a neural-network classifier, and an updated signal extraction strategy adopting a direct binned-likelihood fit to the classifier output. With these improvements, the Higgs boson signal strength is measured to be 0.2 ± 0.7 relative to the Standard Model prediction. This corresponds to an observed significance of 0.3 standard deviations, compared to an expectation of 1.5 standard deviations assuming the Standard Model.

At SK-observable energies, these conversions are dominated by the Mikheyev-Smirnov-Wolfenstein effect. An upturn in the electron neutrino survival probability in which vacuum neutrino oscillations become dominant is predicted to occur at lower energies, but radioactive background increases exponentially with decreasing energy. New machine learning approaches provide substantial background reduction below 3.49 MeV such that statistical extraction of solar neutrino interactions becomes feasible.

Exploring small-angle emissions in charm quark jets in proton-proton collisions at $$ \sqrt{s}=5.02 $$ TeV

The data corresponding to an integrated luminosity of 301 pb <jats:sup> <jats:italic>−</jats:italic> 1 </jats:sup> were collected by the CMS experiment in 2017. Two jet grooming algorithms, late- <jats:italic>k</jats:italic> <jats:sub>T</jats:sub> and soft drop, are used to study the intrajet radiation pattern using iterative Cambridge-Aachen declustering. The splitting-angle distributions of jets with transverse momentum ( <jats:italic>p</jats:italic> <jats:sub>T</jats:sub> ) of around 100 GeV, obtained with these two algorithms, show that there is a shift of the distribution for jets containing a prompt D <jats:sup>0</jats:sup> meson with respect to inclusive jets. The suppression of emissions at small angles observed in the late- <jats:italic>k</jats:italic> <jats:sub>T</jats:sub> grooming approach is consistent with the dead-cone effect, whereas the similar suppression for splittings selected with the soft-drop algorithm appears to be induced by gluon splitting to charm quark-antiquark pairs at large angles. The measured distributions are corrected to the particle level and can be used to constrain model predic

Searches for B^{0}→K^{+}π^{-}τ^{+}τ^{-} and B_{s}^{0}→K^{+}K^{-}τ^{+}τ^{-} Decays.

, Phys Rev Lett, Vol: 136

The first searches for B^{0}→K^{+}π^{-}τ^{+}τ^{-} and B_{s}^{0}→K^{+}K^{-}τ^{+}τ^{-} decays at the LHCb experiment are conducted with pp collision data corresponding to an integrated luminosity of 5.4 fb^{-1}. The tau leptons are reconstructed using the τ^{+}→μ^{+}ν[over ¯]_{τ}ν_{μ} decay and the results are presented in bins of K^{+}π^{-} or K^{+}K^{-} mass. No signal is observed and upper limits are set on the branching fractions. The searches result in the first upper limits for B^{0}→K^{+}π^{-}τ^{+}τ^{-} decays outside the K^{*}(892)^{0} region in K^{+}π^{-} mass and the first limits for B_{s}^{0}→K^{+}K^{-}τ^{+}τ^{-} decays. The searches are recast into limits on the decays B^{0}→K^{*}(892)^{0}τ^{+}τ^{-} and B_{s}^{0}→ϕ(1020)τ^{+}τ^{-}, yielding 2.8×10^{-4} (2.5×10^{-4}) and 4.7×10^{-4} (4.1×10^{-4}) at the 95% (90%) confidence level, respectively. For the decay B^{0}→K^{*}(892)^{0}τ^{+}τ^{-}, this result improves on the current best upper limit by an order of magnitude.

First Evidence for Mixing-Induced CP Violation in B_{s}^{0}→J/ψϕ(1020) Decays in pp Collisions at sqrt[s]=13 TeV.

, Phys Rev Lett, Vol: 136

A novel machine-learning-based flavor-tagging algorithm combining same-side and opposite-side tagging is used to obtain the equivalent of 27 500 tagged B_{s}^{0}→J/ψϕ(1020) decays from pp collisions at sqrt[s]=13 TeV, collected by the CMS experiment and corresponding to an integrated luminosity of 96.5 fb^{-1}. A time- and flavor-dependent angular analysis of the μ^{+}μ^{-}K^{+}K^{-} final state, consistent with a ϕ(1020)→K^{+}K^{-} decay, is used to measure parameters of the B_{s}^{0}-B[over ¯]_{s}^{0} system. The weak phase is measured to be ϕ_{s}=-73±22(stat)±10(syst) mrad, which, combined with the sqrt[s]=8 TeV CMS result, gives ϕ_{s}=-75±23 mrad. This value differs from zero by 3.2 standard deviations, providing the first evidence for mixing-induced CP violation in B_{s}^{0}→J/ψϕ(1020) decays. All measured physics parameters are found to agree with standard model predictions where available.

Inclusive Search for Anomalous Single-Photon Production in MicroBooNE.

, Phys Rev Lett, Vol: 136

We present an inclusive search for anomalous production of single-photon events from neutrino interactions in the MicroBooNE experiment. The search and its signal definition are motivated by the previous observation of a low-energy excess of electromagnetic shower events from the MiniBooNE experiment. We use the Wire-Cell reconstruction framework to select a sample of inclusive single-photon final-state interactions with a final efficiency and purity of 7.0% and 40.2%, respectively. We leverage simultaneous measurements of sidebands of charged current ν_{μ} interactions and neutral current interactions producing π^{0} mesons to constrain signal and background predictions and reduce uncertainties. We perform a blind analysis using a dataset collected from February 2016 to July 2018, corresponding to an exposure of 6.34×10^{20} protons on target from the Booster Neutrino Beam at Fermilab. In the full signal region, we observe agreement between the data and the prediction, with a goodness-of-fit p value of 0.11. We then isolate a subsample of these events containing no visible protons, and observe 93±22(stat)±35(syst) data events above prediction, corresponding to just above 2σ local significance, concentrated at shower energies below 600 MeV.

Search for Light Pseudoscalar Bosons, Pair-Produced in Higgs Boson Decays in the Four-Electron Final State in Proton-Proton Collisions at sqrt[s]=13 TeV.

, Phys Rev Lett, Vol: 136

A search for pairs of light neutral pseudoscalar bosons (A) resulting from the decay of a Higgs boson is performed. The search is conducted using LHC proton-proton 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}. The A boson decays into a highly collimated electron-positron pair. A novel multivariate algorithm using tracks and calorimeter information is developed to identify these distinctive signatures, and events are selected with two such merged electron-positron pairs. No significant excess above the standard model background predictions is observed. Upper limits on the branching fraction for H→AA→4e are set at 95% confidence level, for masses between 10 and 100 MeV and proper decay lengths below 100 μm, reaching branching fraction sensitivities as low as 10^{-5}. This is the first search for Higgs boson decays to four electrons via light pseudoscalars at the LHC. It significantly improves the experimental sensitivity to axionlike particles with masses below 100 MeV .

Characterizing the initial state and dynamical evolution in XeXe and PbPb collisions using multiparticle cumulants

, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 876, ISSN: 0370-2693

For the first time, correlations among mixed-order moments of two or three flow harmonics —(v<inf>n</inf>k,v<inf>m</inf>l) and (v<inf>n</inf>k,v<inf>m</inf>l,v<inf>p</inf>q), with k, l , and q denoting the respective orders—are measured in xenon–xenon (XeXe) collisions and compared with lead–lead (PbPb) results, providing a novel probe of collective behavior in heavy ion collisions. These measurements compare a nearly spherical, doubly-magic 208Pb nucleus to a triaxially deformed 129Xe nucleus, emphasizing the sensitivity to initial-state geometry fluctuations arising from nuclear deformation. The dependence of these results (v<inf>n</inf> , n=2,3,4) on the shape and size of the nuclear overlap region is studied. Comparisons between v <inf>2</inf>, v <inf>3</inf>, and v <inf>4</inf> demonstrate the importance of v <inf>3</inf> and v <inf>4</inf> in exploring the nonlinear hydrodynamic response of the quark-gluon plasma (QGP) to the initial spatial anisotropy. The results constrain initial-state model parameters that influence the evolution of the QGP. The CMS detector was used to collect XeXe and PbPb data at nucleon-nucleon center-of-mass energies of S<inf>NN</inf>=5.44 and 5.36 TeV, respectively. Correlations are extracted using multiparticle mixed-harmonic cumulants (up to eight-particle cumulants) with charged particles in the pseudorapidity range | η | ' 2.4 and transverse momentum range 0.5 ' p<inf>T</inf> ' 3 GeV/c.

Crystals to assist the two-beam merging process in the UA9-apparatus

, Journal of Instrumentation, Vol: 21

The UA9 Collaboration proposes to investigate a two-beam merging process aided by bent crystals in an improved version of an apparatus configured for the H8 beam line at the CERN-SPS North Area. The process involves generating two converging beams which combine inside a curved crystal. The resulting beam should include nearly all the incoming particles and to have a horizontal size almost equivalent to the sum of the converging beams. In practice, the combined beam is formed by horizontal stacking of the two original beams, with no active magnetic elements. Crystals shaped like a C, bent by two screws that compress the ends of the C, exhibit anticlastic bending with parabolic intensities, allowing easy production of the two converging beams and adjustment of their trajectory angles. The merging crystal is made of a short silicon strip to optimize channeling deflection and Multiple Coulomb Scattering. The merging process may be applicable, for instance, in the injector of a muon collider, as the increase in beam intensity occurs over a short distance with a minimal rise in emittance.

First Evidence of the B_{s}^{0}→K^{-}π^{+}γ Decay.

, Phys Rev Lett, Vol: 136

The first search for the B_{s}^{0}→K^{-}π^{+}γ decay in the range 796<m(K^{-}π^{+})<1800 MeV/c^{2} is performed using data from proton-proton collisions collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of 9 fb^{-1}. The photons are reconstructed through their conversion into an electron-positron pair, which significantly improves the mass resolution of the reconstructed decays with respect to decays with an unconverted photon. A signal excess with a significance of 3.5 standard deviations is measured, constituting the first experimental evidence for this decay. In the range 796<m(K^{-}π^{+})<996 MeV/c^{2}, the ratio R between the branching fractions of the signal decay and the favored B[over ¯]^{0}→K^{-}π^{+}γ decay is measured to be R=(3.7±1.2±0.4)×10^{-2} where the first uncertainty is statistical and the second is systematic. This measurement is consistent with the value predicted in the Standard Model. In the range 996<m(K^{-}π^{+})<1800 MeV/c^{2}, the ratio R=(0.2±2.7±1.3)×10^{-2} is measured.

The forward physics facility: Physics opportunities and conceptual design

, Nuclear Physics B, Vol: 1026, ISSN: 0550-3213

The Forward Physics Facility (FPF) is a proposed extension of the HL-LHC program designed to exploit the unique scientific opportunities offered by the intense flux of high energy neutrinos, and possibly new particles, in the far-forward direction. Located in a well-shielded cavern 627 m downstream of one of the LHC interaction points, the facility will support a broad and ambitious physics program that significantly expands the discovery potential of the HL-LHC. Equipped with four complementary detectors—FLArE, FASER ν 2, FASER2, and FORMOSA—the FPF will enable breakthrough measurements that will advance our understanding of neutrino physics, quantum chromodynamics, and astroparticle physics, and will search for dark matter and other new particles. With this Letter of Intent, we propose the construction of the FPF cavern and the construction, integration, and installation of its experiments. We summarize the physics case, the facility design, the layout and components of the detectors, as well as the envisioned collaboration structure, cost estimate, and implementation timeline.

Amplitude analysis of B0→ηc(1S)K+π- decays

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

An amplitude analysis of the B0→ηc(1S)K+π- decays with ηc(1S)→pp¯ is performed using a sample corresponding to an integrated luminosity of 9fb-1 of pp collision data collected by the LHCb detector at centre-of-mass energies of s = 7, 8 and 13TeV. The data are described with a model including only intermediate contributions from known K∗0 resonances. Evidence for an exotic resonance in the ηc(1S)π- system, reported in a previous analysis of this decay channel, is not confirmed. The inclusive branching fraction of the B0→ηc(1S)K+π- decays is measured to be (Formula presented.) where the first uncertainty is statistical, the second systematic, and the third arises from the limited knowledge of external branching fractions.

Precision Measurement of CP Violation and Branching Fractions in B^{±}→K_{S}^{0}h^{±} (h=π, K) Decays and Search for the Rare Decay B_{c}^{±}→K_{S}^{0}K^{±}.

, Phys Rev Lett, Vol: 136

The decay B^{±}→K_{S}^{0}π^{±}, with a CP asymmetry expected to be close to zero in the standard model, is theoretically clean and sensitive to potential new physics. An analysis of the decays B^{±}→K_{S}^{0}π^{±} and B^{±}→K_{S}^{0}K^{±} is performed using proton-proton collision data collected by the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb^{-1}. The CP asymmetries are determined to be A^{CP}(B^{±}→K_{S}^{0}π^{±})=-0.028±0.009±0.009 and A^{CP}(B^{±}→K_{S}^{0}K^{±})=0.118±0.062±0.031, and the branching fraction ratio is measured to be B(B^{±}→K_{S}^{0}K^{±})/B(B^{±}→K_{S}^{0}π^{±})=0.055±0.004±0.002, where the first uncertainties are statistical and the second are systematic. These results are the most precise measurements of these quantities to date. A search for the rare decay B_{c}^{±}→K_{S}^{0}K^{±} is also performed.

Observation of Suppressed Charged-Particle Production in Ultrarelativistic Oxygen-Oxygen Collisions.

, Phys Rev Lett, Vol: 136

A hot and dense state of nuclear matter, known as the quark-gluon plasma, is created in collisions of ultrarelativistic heavy nuclei. Highly energetic quarks and gluons, collectively referred to as partons, lose energy as they travel through this matter, leading to suppressed production of particles with large transverse momenta (p_{T}). Conversely, high-p_{T} particle suppression has not been seen in proton-lead collisions, raising questions regarding the minimum system size required to observe parton energy loss. Oxygen-oxygen (OO) collisions examine a region of effective system size that lies between these two extreme cases. The CMS detector at the CERN LHC has been used to quantify charged-particle production in inclusive OO collisions for the first time via measurements of the nuclear modification factor (R_{AA}). The R_{AA} is derived by comparing particle production to expectations based on proton-proton (pp) data and has a value of unity in the absence of nuclear effects. The data for OO and pp collisions at a nucleon-nucleon center-of-mass energy sqrt[s_{NN}]=5.36 TeV correspond to integrated luminosities of 6.1 nb^{-1} and 1.02 pb^{-1}, respectively. The R_{AA} is below unity with a minimum of 0.69±0.04 around p_{T}=6 GeV. The data exhibit better agreement with theoretical models incorporating parton energy loss as compared to baseline models without energy loss.

Observation of In-Ice Askaryan Radiation from High-Energy Cosmic Rays.

, Phys Rev Lett, Vol: 136

We present the first experimental evidence for in-ice Askaryan radiation-coherent charge-excess radio emission-from high-energy particle cascades developing in the Antarctic ice sheet. In 208 days of data recorded with the phased array instrument of the Askaryan Radio Array, a previous analysis has incidentally identified 13 events with impulsive radio frequency signals originating from below the ice surface. We here present a detailed reanalysis of these events. The observed event rate, radiation arrival directions, signal shape, spectral content, and electric field polarization are consistent with in-ice Askaryan radiation from cosmic ray air shower cores impacting the ice sheet. For the brightest events, the angular radiation pattern favors an extended cascadelike emitter over a pointlike source. An origin from the geomagnetic separation of charges in cosmic ray air showers is disfavored by the arrival directions and polarization. Considering the arrival angles, timing properties, and impulsive nature of the passing events, the event rate is inconsistent with the estimation of the combined background from thermal noise events and on-surface events at the level of 5.1σ.

Search for light pseudoscalar boson pairs produced from Higgs boson decays using the 4τ and 2μ2τ final states 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 pair of light pseudoscalar bosons (a <jats:sub>1</jats:sub> ) produced in the decay of the 125 GeV Higgs boson is presented. The analysis examines decay modes where one a <jats:sub>1</jats:sub> decays into a pair of tau leptons and the other decays into either another pair of tau leptons or a pair of muons. The a <jats:sub>1</jats:sub> boson mass probed in this study ranges from 4 to 15 GeV. The data sample was recorded by the CMS experiment in proton-proton collisions at a center-of-mass energy of 13 TeV and corresponds to an integrated luminosity of 138 fb <jats:sup> <jats:italic>−</jats:italic> 1 </jats:sup> . No excess above standard model (SM) expectations is observed. The study combines the 4τ and 2μ2τ channels to set upper limits at 95% confidence level (CL) on the product of the Higgs boson production cross section and the branching fraction to the 4τ final state, relative to the Higgs boson production cross section predicted by the SM. In this interpretation, the a <jats:sub>1</jats:sub> boson is assumed to have Yukawa-like couplings to fermions, with coupling strengths proportional to the respective fermion masses. The observed (expected) upper limits range between 0.007 (0.011) and 0.079 (0.066) across the mass range considered. The results are also interpreted in the context of models with two Higgs doublets and an additional complex singlet field (2HD+S). The tightest constraints are obtained for the Type III 2HD+S mod

<jats:title> A <jats:sc>bstract</jats:sc> </jats:title> <jats:p> Precision measurements of Higgs boson differential production cross sections are a key tool to probe the properties of the Higgs boson and test the standard model. New physics can affect both Higgs boson production and decay, leading to deviations from the distributions that are expected in the standard model. In this paper, combined measurements of differential spectra in a fiducial region matching the experimental selections are performed, based on analyses of four Higgs boson decay channels (γγ, ZZ <jats:sup>(*)</jats:sup> , WW <jats:sup>(*)</jats:sup> , and ττ) using proton-proton collision data recorded with the CMS detector at <jats:inline-formula> <jats:alternatives> <jats:tex-math>$$ \sqrt{s}=13 $$</jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> <mml:mo>=</mml:mo> <mml:mn>13</mml:mn> </mml:math> </jats:alternatives> </jats:inline-formula> TeV, corresponding to an integrated luminosity of 138 fb <jats:sup> <jats:italic>−</jats:italic> 1 </jats:sup> .
