    Search for high-mass resonances decaying to a jet and aLorentz-boosted resonance in proton-proton collisions at √s = 13 TeV

    , Physics Letters B, Vol: 832, Pages: 1-24, ISSN: 0370-2693

    A search is reported for high-mass hadronic resonances that decay to a parton and a Lorentz-boosted resonance, which in turn decays into a pair of partons. The search is based on data collected with the CMS detector at the LHC in proton-proton collisions at , corresponding to an integrated luminosity of 138. The boosted resonance is reconstructed as a single wide jet with substructure consistent with a two-body decay. The high-mass resonance is thus considered as a dijet system. The jet substructure information and the kinematic properties of cascade resonance decays are exploited to disentangle the signal from the large quantum chromodynamics multijet background. The dijet mass spectrum is analyzed for the presence of new high-mass resonances, and is found to be consistent with the standard model background predictions. Results are interpreted in a warped extra dimension model where the high-mass resonance is a Kaluza–Klein gluon, the boosted resonance is a radion, and the final state partons are all gluons. Limits on the production cross section are set as a function of the Kaluza–Klein gluon and radion masses. These limits exclude at 95% confidence level models with Kaluza–Klein gluon masses in the range 2.0 to 4.3 TeV and radion masses in the range 0.20 to 0.74 TeV. By exploring a novel experimental signature, the observed limits on the Kaluza–Klein gluon mass are extended by up to about 1 TeV compared to previous searches.

    Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC

    , European Physical Journal C: Particles and Fields, Vol: 82, ISSN: 1124-1861

    DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 × 6 × 6 m3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019–2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties.

    Search for flavor-changing neutral current interactions of the top quark and Higgs Boson in final states with two photons in proton-proton collisions at sqrt[s]=13  TeV.

    , Physical Review Letters, Vol: 129, Pages: 1-20, ISSN: 0031-9007

    Proton-proton interactions resulting in final states with two photons are studied in a search for the signature of flavor-changing neutral current interactions of top quarks (t) and Higgs bosons (H). The analysis is based on data collected at a center-of-mass energy of 13 TeV with the CMS detector at the LHC, corresponding to an integrated luminosity of 137  fb^{-1}. No significant excess above the background prediction is observed. Upper limits on the branching fractions (B) of the top quark decaying to a Higgs boson and an up (u) or charm (c) quark are derived through a binned fit to the diphoton invariant mass spectrum. The observed (expected) 95% confidence level upper limits are found to be 0.019% (0.031%) for B(t→Hu) and 0.073% (0.051%) for B(t→Hc). These are the strictest upper limits yet determined.

    Probing charm quark dynamics via multiparticle correlations in Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV

    , Physical Review Letters, Vol: 129, ISSN: 0031-9007

    Multiparticle azimuthal correlations of prompt D^{0} mesons are measured in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of sqrt[s_{NN}]=5.02  TeV. For the first time, a four-particle cumulant method is used to extract the second Fourier coefficient of the azimuthal distribution (v_{2}) of D^{0} mesons as a function of event centrality and the D^{0} transverse momentum. The ratios of the four-particle v_{2} values to previously measured two-particle cumulant results provide direct experimental access to event-by-event fluctuations of charm quark azimuthal anisotropies. These ratios are also found to be comparable to those of inclusive charged particles in the event. However, hints of deviations are seen in the most central and peripheral collisions. To investigate the origin of flow fluctuations in the charm sector, these measurements are compared to a model implementing fluctuations of charm quark energy loss via collisional or radiative processes in the quark-gluon plasma. These models cannot quantitatively describe the data over the full transverse momentum and centrality ranges, although the calculations with collisional energy loss provide a better description of the data.

    Search for resonances decaying to three W bosons in proton-proton collisions at sqrt[s]=13  TeV

    , Physical Review Letters, Vol: 129, ISSN: 0031-9007

    A search for resonances decaying into a W boson and a radion, where the radion decays into two W bosons, is presented. The data analyzed correspond to an integrated luminosity of 138  fb^{-1} recorded in proton-proton collisions with the CMS detector at sqrt[s]=13  TeV. One isolated charged lepton is required, together with missing transverse momentum and one or two massive large-radius jets, containing the decay products of either two or one W bosons, respectively. No excess over the background estimation is observed. The results are combined with those from a complementary channel with an all-hadronic final state, described in an accompanying paper. Limits are set on parameters of an extended warped extra-dimensional model. These searches are the first of their kind at the LHC.

    Identification of hadronic tau lepton decays using a deep neural network

    , Journal of Instrumentation, Vol: 17, Pages: P07023-P07023

    <jats:title>Abstract</jats:title> <jats:p>A new algorithm is presented to discriminate reconstructed hadronic decays of tau leptons (<jats:italic>τ</jats:italic> <jats:sub>h</jats:sub>) that originate from genuine tau leptons in the CMS detector against <jats:italic>τ</jats:italic> <jats:sub>h</jats:sub> candidates that originate from quark or gluon jets, electrons, or muons. The algorithm inputs information from all reconstructed particles in the vicinity of a <jats:italic>τ</jats:italic> <jats:sub>h</jats:sub> candidate and employs a deep neural network with convolutional layers to efficiently process the inputs. This algorithm leads to a significantly improved performance compared with the previously used one. For example, the efficiency for a genuine <jats:italic>τ</jats:italic> <jats:sub>h</jats:sub> to pass the discriminator against jets increases by 10–30% for a given efficiency for quark and gluon jets. Furthermore, a more efficient <jats:italic>τ</jats:italic> <jats:sub>h</jats:sub> reconstruction is introduced that incorporates additional hadronic decay modes. The superior performance of the new algorithm to discriminate against jets, electrons, and muons and the improved <jats:italic>τ</jats:italic> <jats:sub>h</jats:sub> reconstruction method are validated with LHC proton-proton collision data at √<jats:italic>s</jats:italic> = 13 TeV.</jats:p>

    First search for exclusive diphoton production at high mass with tagged protons in proton-proton collisions at sqrt[s]=13  TeV

    , Physical Review Letters, Vol: 129, ISSN: 0031-9007

    A search for exclusive two-photon production via photon exchange in proton-proton collisions, pp→pγγp with intact protons, is presented. The data correspond to an integrated luminosity of 9.4  fb^{-1} collected in 2016 using the CMS and TOTEM detectors at a center-of-mass energy of 13 TeV at the LHC. Events are selected with a diphoton invariant mass above 350 GeV and with both protons intact in the final state, to reduce backgrounds from strong interactions. The events of interest are those where the invariant mass and rapidity calculated from the momentum losses of the forward-moving protons match the mass and rapidity of the central, two-photon system. No events are found that satisfy this condition. Interpreting this result in an effective dimension-8 extension of the standard model, the first limits are set on the two anomalous four-photon coupling parameters. If the other parameter is constrained to its standard model value, the limits at 95% confidence level are |ζ_{1}|<2.9×10^{-13}  GeV^{-4} and |ζ_{2}|<6.0×10^{-13}  GeV^{-4}.

    Search for resonant production of strongly coupled dark matter in proton-proton collisions at 13 TeV

    , The Journal of High Energy Physics, Vol: 2022, Pages: 1-51, ISSN: 1029-8479

    The first collider search for dark matter arising from a strongly coupled hidden sector is presented and uses a data sample corresponding to 138 fb−1, collected with the CMS detector at the CERN LHC, at s√ = 13 TeV. The hidden sector is hypothesized to couple to the standard model (SM) via a heavy leptophobic Z′ mediator produced as a resonance in proton-proton collisions. The mediator decay results in two “semivisible” jets, containing both visible matter and invisible dark matter. The final state therefore includes moderate missing energy aligned with one of the jets, a signature ignored by most dark matter searches. No structure in the dijet transverse mass spectra compatible with the signal is observed. Assuming the Z′ boson has a universal coupling of 0.25 to the SM quarks, an inclusive search, relevant to any model that exhibits this kinematic behavior, excludes mediator masses of 1.5–4.0 TeV at 95% confidence level, depending on the other signal model parameters. To enhance the sensitivity of the search for this particular class of hidden sector models, a boosted decision tree (BDT) is trained using jet substructure variables to distinguish between semivisible jets and SM jets from background processes. When the BDT is employed to identify each jet in the dijet system as semivisible, the mediator mass exclusion increases to 5.1 TeV, for wider ranges of the other signal model parameters.

    Observation of the B_{c}^{+} meson in Pb-Pb and pp collisions at sqrt[s_{NN}]=5.02  TeV and measurement of its nuclear modification factor

    , Physical Review Letters, Vol: 128, ISSN: 0031-9007

    The B_{c}^{+} meson is observed for the first time in heavy ion collisions. Data from the CMS detector are used to study the production of the B_{c}^{+} meson in lead-lead (Pb-Pb) and proton-proton (pp) collisions at a center-of-mass energy per nucleon pair of sqrt[s_{NN}]=5.02  TeV, via the B_{c}^{+}→(J/ψ→μ^{+}μ^{-})μ^{+}ν_{μ} decay. The B_{c}^{+} nuclear modification factor, derived from the Pb-Pb-to-pp ratio of production cross sections, is measured in two bins of the trimuon transverse momentum and of the Pb-Pb collision centrality. The B_{c}^{+} meson is shown to be less suppressed than quarkonia and most of the open heavy-flavor mesons, suggesting that effects of the hot and dense nuclear matter created in heavy ion collisions contribute to its production. This measurement sets forth a promising new probe of the interplay of suppression and enhancement mechanisms in the production of heavy-flavor mesons in the quark-gluon plasma.

    Search for charged-lepton flavor violation in top quark production and decay in pp collisions at root s=13 TeV

    , The Journal of High Energy Physics, Vol: 2022, Pages: 1-43, ISSN: 1029-8479

    Results are presented from a search for charged-lepton flavor violating (CLFV) interactions in top quark production and decay in pp collisions at a center-of-mass energy of 13 TeV. The events are required to contain one oppositely charged electron-muon pair in the final state, along with at least one jet identified as originating from a bottom quark. The data correspond to an integrated luminosity of 138 fb−1, collected by the CMS experiment at the LHC. This analysis includes both the production (q → eμt) and decay (t → eμq) modes of the top quark through CLFV interactions, with q referring to a u or c quark. These interactions are parametrized using an effective field theory approach. With no significant excess over the standard model expectation, the results are interpreted in terms of vector-, scalar-, and tensor-like CLFV four-fermion effective interactions. Finally, observed exclusion limits are set at 95% confidence levels on the respective branching fractions of a top quark to an eμ pair and an up (charm) quark of 0.13 × 10−6 (1.31 × 10−6), 0.07 × 10−6 (0.89 × 10−6), and 0.25 × 10−6 (2.59 × 10−6) for vector, scalar, and tensor CLFV interactions, respectively.

    Optimizing graph Neural Networks for jet tagging in particle physics on FPGAs

    , International Conference on Field Programmable Logic and Applications, Publisher: IEEE

    This work proposes a novel reconfigurable architecture for reducing the latency of JEDI-net, a Graph NeuralNetwork (GNN) based algorithm for jet tagging in particlephysics, which achieves state-of-the-art accuracy. AcceleratingJEDI-net is challenging since it requires low latency to deploythe network for event selection at the CERN Large HadronCollider. This paper proposes an outer-product based matrixmultiplication approach customized for GNN-based JEDI-net,which increases data spatial locality and reduces design latency.It is further enhanced by code transformation with strengthreduction which exploits sparsity patterns and binary adjacencymatrices to increase hardware efficiency while reducing latency.In addition, a customizable template for this architecture hasbeen designed and open-sourced, which enables the generationof low-latency FPGA designs with efficient resource utilizationusing high-level synthesis tools. Evaluation results show that ourFPGA implementation is up to 9.5 times faster and consumes upto 6.5 times less power than a GPU implementation. Moreover,the throughput of our FPGA design is sufficiently high to enabledeployment of JEDI-net in a sub-microsecond, real-time collidertrigger system, enabling it to benefit from improved accuracy.

    Observation of B-s(0) mesons and measurement of the B-s(0)/B+ yield ratio in PbPb collisions at root S-NN=5.02 TeV

    , Modern Physics Letters B, Vol: 829, Pages: 1-25, ISSN: 0217-9849

    The B0s and B+ production yields are measured in PbPb collisions at a center-of-mass energy pernucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, correspondsto an integrated luminosity of 1.7 nb−1. The mesons are reconstructed in the exclusive decay channelsB0s → J/ψ(μ+μ−)φ(K+K−) and B+ → J/ψ(μ+μ−)K+, in the transverse momentum range 7–50 GeV/cand absolute rapidity 0–2.4. The B0s meson is observed with a statistical significance in excess of fivestandard deviations for the first time in nucleus-nucleus collisions. The measurements are performed asfunctions of the transverse momentum of the B mesons and of the PbPb collision centrality. The ratioof production yields of B0s and B+ is measured and compared to theoretical models that include quarkrecombination effects.

    Analysis of the CP structure of the Yukawa coupling between the Higgs boson and tau leptons in proton-proton collisions at root s=13 TeV

    , The Journal of High Energy Physics, Vol: 2022, Pages: 1-67, ISSN: 1029-8479

    The first measurement of the CP structure of the Yukawa coupling between the Higgs boson and τ leptons is presented. The measurement is based on data collected in proton-proton collisions at s√ = 13 TeV by the CMS detector at the LHC, corresponding to an integrated luminosity of 137 fb−1. The analysis uses the angular correlation between the decay planes of τ leptons produced in Higgs boson decays. The effective mixing angle between CP-even and CP-odd τ Yukawa couplings is found to be −1 ± 19°, compared to an expected value of 0 ± 21° at the 68.3% confidence level. The data disfavour the pure CP-odd scenario at 3.0 standard deviations. The results are compatible with predictions for the standard model Higgs boson.

    Search for solar electron anti-neutrinos due to spin-flavor precession in the Sun with Super-Kamiokande-IV

    , Astroparticle Physics, Vol: 139, ISSN: 0927-6505

    Due to a very low production rate of electron anti-neutrinos (ν̄e) via nuclear fusion in the Sun, a flux of solar ν̄e is unexpected. An appearance of ν̄e in solar neutrino flux opens a new window for the new physics beyond the standard model. In particular, a spin-flavor precession process is expected to convert an electron neutrino into an electron anti-neutrino (νe→ν̄e) when neutrino has a finite magnetic moment. In this work, we have searched for solar ν̄e in the Super-Kamiokande experiment, using neutron tagging to identify their inverse beta decay signature. We identified 78 ν̄e candidates for neutrino energies of 9.3 to 17.3 MeV in 2970.1 live days with a fiducial volume of 22.5 kiloton water (183.0 kton⋅year exposure). The energy spectrum has been consistent with background predictions and we thus derived a 90% confidence level upper limit of 4.7×10−4 on the νe→ν̄e conversion probability in the Sun. We used this result to evaluate the sensitivity of future experiments, notably the Super-Kamiokande Gadolinium (SK-Gd) upgrade.
