Measurements of single-, double-, and triple-differential cross-sections are presented for boosted top-quark pair-production in 13 TeV proton–proton collisions recorded by the ATLAS detector at the LHC. The top quarks are observed through their hadronic decay and reconstructed as large-radius jets with the leading jet having transverse momentum (p T) greater than 500 GeV. The observed data are unfolded to remove detector effects. The particle-level cross-section, multiplied by the branching fraction and measured in a fiducial phase space defined by requiring the leading and second-leading jets to have p T> 500 GeV and p T> 350 GeV, respectively, is 331±3 (stat.)±39 (syst.) fb. This is approximately 20% lower than the prediction of fb by P owheg+ P ythia 8 with next-to-leading-order (NLO) accuracy but consistent within the theoretical uncertainties. Results are also presented at the parton level …

We present the first search for the weak radiative decays Λc+→ ς+ γ and Ξc0→ Ξ0γ using a data sample of 980 fb-1 collected by the Belle detector operating at the KEKB asymmetric-energy e+ e-collider. There are no evident Λc+→ ς+ γ or Ξc0→ Ξ0γ signals. Taking the decays Λc+→ pK-π+ and Ξc0→ Ξ-π+ as normalization channels, the upper limits at 90% credibility level on the ratios of branching fractions B (Λc+→ ς+ γ)/B (Λc+→ pK-π+)< 4.0× 10-3 and B (Ξc0→ Ξ0γ)/B (Ξc0→ Ξ-π+)< 1.2× 10-2 are determined. We obtain the upper limits at 90% credibility level on the absolute branching fractions B (Λc+→ ς+ γ)< 2.6× 10-4 and B (Ξc0→ Ξ0γ)< 1.8× 10-4.

A search for low-mass dilepton resonances in Higgs boson decays is conducted in the four-lepton final state. The decay is assumed to proceed via a pair of beyond the standard model particles, or one such particle and a boson. The search uses proton–proton collision data collected with the CMS detector at the CERN LHC, corresponding to an integrated luminosity of 137, at a center-of-mass energy . No significant deviation from the standard model expectation is observed. Upper limits at 95% confidence level are set on model-independent Higgs boson decay branching fractions. Additionally, limits on dark photon and axion-like particle production, based on two specific models, are reported.

Measurements of the production cross-sections of the Standard Model (SM) Higgs boson () decaying into a pair of -leptons are presented. The measurements use data collected with the ATLAS detector from collisions produced at the Large Hadron Collider at a centre-of-mass energy of , corresponding to an integrated luminosity of . Leptonic () and hadronic () decays of the -lepton are considered. All measurements account for the branching ratio of and are performed with a requirement , where is the true Higgs boson rapidity. The cross-section of the process is measured to be pb, in agreement with the SM prediction of pb. Inclusive cross-sections are determined separately for the four dominant production modes: pb for gluongluon fusion, pb for vector-boson fusion, pb for vector-boson associated production, and pb for top-quark pair associated production. Measurements in exclusive regions of the phase space, using the simplified template cross-section framework, are also performed. All results are in agreement with the SM predictions.

The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino oscillation experiment with a primary physics goal of observing neutrino and antineutrino oscillation patterns to precisely measure the parameters governing long-baseline neutrino oscillation in a single experiment, and to test the three-flavor paradigm. DUNE's design has been developed by a large, international collaboration of scientists and engineers to have unique capability to measure neutrino oscillation as a function of energy in a broadband beam, to resolve degeneracy among oscillation parameters, and to control systematic uncertainty using the exquisite imaging capability of massive LArTPC far detector modules and an argon-based near detector. DUNE's neutrino oscillation measurements will unambiguously resolve the neutrino mass ordering and provide the sensitivity to discover CP violation in neutrinos for a wide range of possible values of . DUNE is also uniquely sensitive to electron neutrinos from a galactic supernova burst, and to a broad range of physics beyond the Standard Model (BSM), including nucleon decays. DUNE is anticipated to begin collecting physics data with Phase I, an initial experiment configuration consisting of two far detector modules and a minimal suite of near detector components, with a 1.2 MW proton beam. To realize its extensive, world-leading physics potential requires the full scope of DUNE be completed in Phase II. The three Phase II upgrades are all necessary to achieve DUNE's physics goals: (1) addition of far detector modules three and four for a total FD fiducial mass of at least 40 kt, (2 …

During the upcoming High Luminosity phase of the Large Hadron Collider (HL-LHC), the integrated luminosity of the accelerator will increase to 3000 fb− 1. The expected experimental conditions in that period in terms of background rates, event pileup, and the probable aging of the current detectors present a challenge for all the existing experiments at the LHC, including the Compact Muon Solenoid (CMS) experiment. To ensure a highly performing muon system for this period, several upgrades of the Resistive Plate Chamber (RPC) system of the CMS are currently being implemented. These include the replacement of the readout system for the present system, and the installation of two new RPC stations with improved chamber and front-end electronics designs. The current overall status of this CMS RPC upgrade project is presented.

The B s 0 and B+ production yields are measured in PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, corresponds to an integrated luminosity of 1.7 nb− 1. The mesons are reconstructed in the exclusive decay channels B→ s 0 J/ψ (μ+ μ−) ϕ (K+ K−) and B→+ J/ψ (μ+ μ−) K+, in the transverse momentum range 7–50 GeV/c and absolute rapidity 0–2.4. The B s 0 meson is observed with a statistical significance in excess of five standard deviations for the first time in nucleus-nucleus collisions. The measurements are performed as functions of the transverse momentum of the B mesons and of the PbPb collision centrality. The ratio of production yields of B s 0 and B+ is measured and compared to theoretical models that include quark recombination effects.

A search for resonant Higgs boson pair production in the b (b) over barb (b) over bar final state is presented. The analysis uses 126 fb (-1)-139 fb (-1) of pp collision data at root s= 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis is divided into two channels, targeting Higgs boson decays which are reconstructed as pairs of small-radius jets or as individual large-radius jets. Spin-0 and spin2 benchmark signal models are considered, both of which correspond to resonant HH production via gluon-gluon fusion. The data are consistent with Standard Model predictions. Upper limits are set on the production cross section times branching ratio to Higgs boson pairs of a new resonance in the mass range from 251 GeV to 5 TeV.

In order to deal with the very high interaction multiplicities per bunch crossing expected with the 13 TeV collisions the inner detector trigger was redesigned during the long shutdown of the Large Hadron Collider from 2013 until 2015. An overview of these developments is provided and the performance of the tracking in the trigger for the muon, electron, tau and b-jet signatures is discussed. The high performance of the inner detector trigger with these extreme interaction multiplicities demonstrates how the inner detector tracking continues to lie at the heart of …

A measurement of inclusive and differential fiducial cross-sections for the production of the Higgs boson decaying into two photons is performed using 139 fb− 1 of proton-proton collision data recorded at= 13 TeV by the ATLAS experiment at the Large Hadron Collider. The inclusive cross-section times branching ratio, in a fiducial region closely matching the experimental selection, is measured to be 67±6 fb, which is in agreement with the state-of-the-art Standard Model prediction of 64±4 fb. Extrapolating this result to the full phase space and correcting for the branching ratio, the total cross-section for Higgs boson production is estimated to be 58±6 pb. In addition, the cross-sections in four fiducial regions sensitive to various Higgs boson production modes and differential cross-sections as a function of either one or two of several observables are measured. All the measurements are found to be in agreement …

A simultaneous measurement of the three components of the top-quark and top-antiquark polarisation vectors in t-channel single-top-quark production is presented. This analysis is based on data from proton–proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 139 fb− 1, collected with the ATLAS detector at the LHC. Selected events contain exactly one isolated electron or muon, large missing transverse momentum and exactly two jets, one being b-tagged. Stringent selection requirements are applied to discriminate t-channel single-top-quark events from the background contributions. The top-quark and top-antiquark polarisation vectors are measured from the distributions of the direction cosines of the charged-lepton momentum in the top-quark rest frame. The three components of the polarisation vector for the selected top-quark event sample are= 0. 01±0. 18,=− 0. 029±0. 027 …

A search for W γ resonances in the mass range between 0.7 and 6.0 TeV is presented. The W boson is reconstructed via its hadronic decays, with the final-state products forming a single large-radius jet, owing to a high Lorentz boost of the W boson. The search is based on proton-proton collision data at s= 13 TeV, corresponding to an integrated luminosity of 137 fb− 1, collected with the CMS detector at the LHC in 2016–2018. The W γ mass spectrum is parameterized with a smoothly falling background function and examined for the presence of resonance-like signals. No significant excess above the predicted background is observed. Model-specific upper limits at 95% confidence level on the product of the cross section and branching fraction to the W γ channel are set. Limits for narrow resonances and for resonances with an intrinsic width equal to 5% of their mass, for spin-0 and spin-1 hypotheses, range …

The first evidence for X (3872) production in relativistic heavy ion collisions is reported. The X (3872) production is studied in lead-lead (Pb-Pb) collisions at a center-of-mass energy of s NN= 5.02 TeV per nucleon pair, using the decay chain X (3872)→ J/ψ π+ π−→ μ+ μ− π+ π−. The data were recorded with the CMS detector in 2018 and correspond to an integrated luminosity of 1.7 nb− 1. The measurement is performed in the rapidity and transverse momentum ranges| y|< 1.6 and 15< p T< 50 GeV/c. The significance of the inclusive X (3872) signal is 4.2 standard deviations. The prompt X (3872) to ψ 2 S yield ratio is found to be ρ Pb− Pb= 1.08±0.49 (stat)±0.52 (syst), to be compared with typical values of 0.1 for p p collisions. This result provides a unique experimental input to theoretical models of the X (3872) production mechanism, and of the nature of this exotic state.

A measurement of the energy asymmetry in jet-associated top-quark pair production is presented using of data collected by the ATLAS detector at the Large Hadron Collider during pp collisions at. The observable measures the different probability of top and antitop quarks to have the higher energy as a function of the jet scattering angle with respect to the beam axis. The energy asymmetry is measured in the semileptonic decay channel, and the hadronically decaying top quark must have transverse momentum above. The results are corrected for detector effects to particle level in three bins of the scattering angle of the associated jet. The measurement agrees with the SM prediction at next-to-leading-order accuracy in quantum chromodynamics in all three bins. In the bin with the largest expected asymmetry, where the jet is emitted perpendicular to the beam, the energy asymmetry is measured to …

The ProtoDUNE-SP detector is a single-phase liquid argon time projection chamber (LArTPC) that was constructed and operated in the CERN North Area at the end of the H4 beamline. This detector is a prototype for the first far detector module of the Deep Underground Neutrino Experiment (DUNE), which will be constructed at the Sandford Underground Research Facility (SURF) in Lead, South Dakota, USA The ProtoDUNE-SP detector incorporates full-size components as designed for DUNE and has an active volume of 7× 6× 7.2 m^{3}. The H4 beam delivers incident particles with well-measured momenta and high-purity particle identification. ProtoDUNE-SP's successful operation between 2018 and 2020 demonstrates the effectiveness of the single-phase far detector design. This paper describes the design, construction, assembly and operation of the detector components.

Production cross sections of (1S), (2S), and (3S) states decaying into in proton-lead (pPb) collisions are reported using data collected by the CMS experiment at 5.02 TeV. A comparison is made with corresponding cross sections obtained with pp data measured at the same collision energy and scaled by the Pb nucleus mass number. The nuclear modification factor for (1S) is found to be = 0.806 0.024 (stat) 0.059 (syst). Similar results for the excited states indicate a sequential suppression pattern, such that . The suppression is much less pronounced in pPb than in PbPb collisions, and independent of transverse momentum and center-of-mass rapidity of the individual state in the studied range 30 GeV and 1.93. Models that incorporate sequential suppression of bottomonia in pPb collisions are in better agreement with the data than those which only assume initial-state modifications.

Heavy-flavour hadron production provides information about the transport properties and microscopic structure of the quark–gluon plasma created in ultra-relativistic heavy-ion collisions. A measurement of the muons from semileptonic decays of charm and bottom hadrons produced in Pb+ Pb and pp collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV with the ATLAS detector at the Large Hadron Collider is presented. The Pb+ Pb data were collected in 2015 and 2018 with sampled integrated luminosities of 208 μ b− 1 and 38 μ b− 1, respectively, and pp data with a sampled integrated luminosity of 1.17 pb− 1 were collected in 2017. Muons from heavy-flavour semileptonic decays are separated from the light-flavour hadronic background using the momentum imbalance between the inner detector and muon spectrometer measurements, and muons originating from charm and bottom decays are …
