Measurements of properties of the Higgs boson decaying to a W boson pair in pp collisions at s=13TeV
(2019)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsMeasurements of the production of the standard model Higgs boson decaying to a W boson pair are reported. The W+W- candidates are selected in events with an oppositely charged lepton pair, large missing transverse momentum, and various numbers of jets. To select Higgs bosons produced via vector boson fusion and associated production with a W or Z boson, events with two jets or three or four leptons are also selected. The event sample ...Journal Article -

Constraints on anomalous HVV couplings from the production of Higgs bosons decaying to τ lepton pairs
(2019)Physical Review DA study is presented of anomalous HVV interactions of the Higgs boson, including its CP properties. The study uses Higgs boson candidates produced mainly in vector boson fusion and gluon fusion that subsequently decay to a pair of τ leptons. The data were recorded by the CMS experiment at the LHC in 2016 at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 35.9 fb-1. A matrix element technique is employed for ...Journal Article -
Search for narrow Hγ resonances in proton-proton collisions at s =13 TeV
(2019)Physical Review LettersA search for heavy, narrow resonances decaying to a Higgs boson and a photon (Hγ) has been performed in proton-proton collision data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1 collected with the CMS detector at the LHC in 2016. Events containing a photon and a Lorentz-boosted hadronically decaying Higgs boson reconstructed as a single, large-radius jet are considered, and the γ+jet invariant ...Journal Article -
Search for supersymmetric partners of electrons and muons in proton–proton collisions at √s = 13 TeV
(2019)Physics Letters BA search for direct production of the supersymmetric (SUSY) partners of electrons or muons is presented in final states with two opposite-charge, same-flavour leptons (electrons and muons), no jets, and large missing transverse momentum. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton–proton collisions at √s = 13 TeV, collected with the CMS detector at the LHC in 2016. The search uses the MT2 variable, which ...Journal Article -
Probing the chiral magnetic wave in pPb and PbPb collisions at sNN =5.02 TeV using charge-dependent azimuthal anisotropies
(2019)Physical Review CCharge-dependent anisotropy Fourier coefficients (vn) of particle azimuthal distributions are measured in pPb and PbPb collisions at √sNN=5.02TeV with the CMS detector at the LHC. The normalized difference in the second-order anisotropy coefficients (v2) between positively and negatively charged particles is found to depend linearly on the observed event charge asymmetry with comparable slopes for both pPb and PbPb collisions over a wide ...Journal Article -
Measurement of differential cross sections for inclusive isolated-photon and photon plus jet production in proton-proton collisions at root s=13TeV
(2019)The European Physical Journal CMeasurements of inclusive isolated-photon and photon+jet production in proton–proton collisions at s√=13TeV are presented. The analysis uses data collected by the CMS experiment in 2015, corresponding to an integrated luminosity of 2.26fb−1. The cross section for inclusive isolated photon production is measured as a function of the photon transverse energy in a fiducial region. The cross section for photon+jet production is measured as a ...Journal Article -
Non-Gaussian elliptic-flow fluctuations in PbPb collisions at √sNN = 5.02 TeV
(2019)Physics Letters BEvent-by-event fluctuations in the elliptic-flow coefficient v2 are studied in PbPb collisions at √sNN=5.02 TeV using the CMS detector at the CERN LHC. Elliptic-flow probability distributions p(v2) for charged particles with transverse momentum 0.3<pT<3.0 GeV/c and pseudorapidity |η|<1.0 are determined for different collision centrality classes. The moments of the p(v2) distributions are used to calculate the v2 coefficients based on ...Journal Article -
Search for long-lived particles decaying into displaced jets in proton-proton collisions at root s=13 TeV
(2019)Physical Review DA search for long-lived particles decaying into jets is presented. Data were collected with the CMS detector at the LHC from proton-proton collisions at a center-of-mass energy of 13 TeV in 2016, corresponding to an integrated luminosity of 35.9 fb−1. The search examines the distinctive topology of displaced tracks and secondary vertices. The selected events are found to be consistent with standard model predictions. For a simplified ...Journal Article -
Pseudorapidity distributions of charged hadrons in xenon-xenon collisions at sNN=5.44 TeV
(2019)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsMeasurements of the pseudorapidity distributions of charged hadrons produced in xenon-xenon collisions at a nucleon-nucleon centre-of-mass energy of sNN=5.44 TeV are presented.
