Measurement of B0s meson production in pp and PbPb collisionsat √sNN=5.02 TeV
(2019)Physics Letters BThe production cross sections of Bs 0 mesons and charge conjugates are measured in proton-proton (pp) and PbPb collisions via the exclusive decay channel Bs 0→J/ψϕ→μ+μ−K+K− at a center-of-mass energy of 5.02 TeV per nucleon pair and within the rapidity range |y|<2.4 using the CMS detector at the LHC. The pp measurement is performed as a function of transverse momentum (pT) of the Bs 0 mesons in the range of 7 to 50 GeV/c and is compared ...Journal Article -
Evidence for light-by-light scattering and searches for axion-like particles in ultraperipheral PbPb collisions at √sNN=5.02TeV
(2019)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsEvidence for the light-by-light scattering process, γγ→γγ , in ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of is reported. The analysis is conducted using a data sample corresponding to an integrated luminosity of 390 μb−1 recorded by the CMS experiment at the LHC. Light-by-light scattering processes are selected in events with two photons exclusively produced, each with transverse energy EγT>2GeV, ...Journal Article -
Studies of Beauty Suppression via Nonprompt D0 Mesons in Pb-Pb Collisions at √sNN=5.02 TeV
(2019)Physical Review LettersThe transverse momentum spectra of D0 mesons from b hadron decays are measured at midrapidity (|y|<1) in pp and Pb-Pb collisions at a nucleon-nucleon center of mass energy of 5.02 TeV with the CMS detector at the LHC. The D0 mesons from b hadron decays are distinguished from prompt D0 mesons by their decay topologies. In Pb-Pb collisions, the B→D0 yield is found to be suppressed in the measured pT range from 2 to 100 GeV/c as compared ...Journal Article -
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 -
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 -
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.
