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 -
Pseudorapidity and transverse momentum dependence of flow harmonics in p Pb and PbPb collisions
(2018)Physical Review CMeasurements of azimuthal angular correlations are presented for high-multiplicity pPb collisions at √sNN=5.02TeV and peripheral PbPb collisions at √sNN=2.76TeV. The data used in this work were collected with the Compact Muon Solenoid (CMS) detector at the European Organization for Nuclear Research (CERN) Large Hadron Collider (LHC). Fourier coefficients as functions of transverse momentum and pseudorapidity are studied using the scalar ...Journal Article -
Nuclear modification factor of D0 mesons in PbPb collisions at 𝑠NN‾‾‾‾√=5.02 TeV
(2018)Physics Letters BThe transverse momentum (pT) spectrum of prompt D0 mesons and their antiparticles has been measured via the hadronic decay channels D0 -> K-π+ and D0 -> K+π- in pp and PbPb collisions at a centre-of-mass energy of 5.02 TeV per nucleon pair with the CMS detector at the LHC. The measurement is performed in the D0 meson range of 2–100 GeV/c and in the rapidity range of y < 1 . The pp(PbPb) dataset used for this analysis corresponds to an ...Journal Article -
Measurement of the underlying event activity in inclusive Z boson production in proton-proton collisions at √s=13 TeV
(2018)Journal of High Energy PhysicsThis paper presents a measurement of the underlying event activity in proton-proton collisions at a center-of-mass energy of 13 TeV, performed using inclusive Z boson production events collected with the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 2.1 fb−1. The underlying event activity is quantified in terms of the charged particle multiplicity, as well as of the scalar sum of the charged ...Journal Article -
Bose-Einstein correlations in pp, pPb, and PbPb collisions at √sN N = 0.9–7 TeV
(2018)Physical Review CQuantum-statistical (Bose-Einstein) two-particle correlations are measured in pp collisions at √s=0.9, 2.76, and 7 TeV, as well as in pPb and peripheral PbPb collisions at nucleon-nucleon center-of-mass energies of 5.02 and 2.76 TeV, respectively, using the CMS detector at the Large Hadron Collider. Separate analyses are performed for same-sign unidentified charged particles as well as for same-sign pions and kaons identified via their ...Journal Article -
Measurement of Prompt D0 Meson Azimuthal Anisotropy in Pb-Pb Collisions at √sNN=5.02 TeV
(2018)Physical Review LettersThe prompt D0 meson azimuthal anisotropy coefficients, v2 and v3, are measured at midrapidity (|y|<1.0) in Pb-Pb collisions at a center-of-mass energy √sNN=5.02 TeV per nucleon pair with data collected by the CMS experiment. The measurement is performed in the transverse momentum (pT) range of 1 to 40 GeV/c, for central and midcentral collisions. The v2 coefficient is found to be positive throughout the pT range studied. The first ...Journal Article -
Search for new long-lived particles at √ s =13 TeV
(2018)Physics Letters BThe observation of physics beyond the standard model (BSM) is one of the main objectives of the ATLAS and CMS experiments at the CERN LHC. With no signal yet observed, these experiments have placed stringent bounds on BSM models. The majority of these searches focus on particles with lab frame decay lengths of mm and incorporate selection requirements that reject longer-lived particle decays. This leaves open the possibility that long-lived ...Journal Article -
Search for supersymmetry in events with one lepton and multiple jets exploiting the angular correlation between the lepton and the missing transverse momentum in proton–proton collisions at √s =13TeV
(2018)Physics Letters BResults are presented from a search for supersymmetry in events with a single electron or muon and hadronic jets. The data correspond to a sample of proton–proton collisions at √s =13TeV with an integrated luminosity of 35.9fb-1, recorded in 2016 by the CMS experiment. A number of exclusive search regions are defined according to the number of jets, the number of b -tagged jets, the scalar sum of the transverse momenta of the jets, and ...Journal Article -
