Correlations of azimuthal anisotropy Fourier harmonics with subevent cumulants in pPb collisions at sNN =8.16 TeV
(2021)Physical Review CEvent-by-event long-range correlations of azimuthal anisotropy Fourier coefficients (vn) in 8.16 TeV pPb data, collected by the CMS experiment at the CERN Large Hadron Collider, are extracted using a subevent four-particle cumulant technique applied to very low multiplicity events. Each combination of four charged particles is selected from either two, three, or four distinct subevent regions of a pseudorapidity range from −2.4 to 2.4 of ...Journal Article -
Measurement of single-diffractive dijet production in proton-proton collisions at √s= 8 TeV with the CMS and TOTEM experiments
(2020)The European Physical Journal CMeasurements are presented of the single-diffractive dijet cross section and the diffractive cross section as a function of the proton fractional momentum loss xi and the four-momentum transfer squared t. Both processes pp -> pX and pp -> Xp, i.e. with the proton scattering to either side of the interaction point, are measured, where X includes at least two jets; the results of the two processes are averaged. The analyses are based on ...Journal Article -
Search for a light charged Higgs boson in the H±→cs channel in proton-proton collisions at √s=13 TeV
(2020)Physical Review DA search is conducted for a low-mass charged Higgs boson produced in a top quark decay and subsequently decaying into a charm and a strange quark. The data sample was recorded in proton-proton collisions at root s = 13 TeV by the CMS experiment at the LHC and corresponds to an integrated luminosity of 35.9 fb(-1). The search is performed in the process of top quark pair production, where one top quark decays to a bottom quark and a charged ...Journal Article -
Studies of Charm Quark Diffusion inside Jets Using Pb-Pb and pp Collisions at root s(NN)=5.02 TeV
(2020)Physical Review LettersThe first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with pjetT>60 GeV/c and D0 mesons with pDT>4 GeV/c in lead-lead (Pb-Pb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of √sNN=5.02 TeV, recorded by the CMS detector at the LHC. The radial distribution of D0 mesons with respect to the jet axis is sensitive to ...Journal Article -
Strange hadron production in pp and pPb collisions at sNN =5.02 TeV
(2020)Physical Review CThe transverse momentum (pT) distributions of Λ, Ξ-, and ω- baryons, their antiparticles, and KS0 mesons are measured in proton-proton (pp) and proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV over a broad rapidity range. The data, corresponding to integrated luminosities of 40.2 nb-1 and 15.6 μb-1 for pp and pPb collisions, respectively, were collected by the CMS experiment. The nuclear modification ...Journal Article -
Search for light pseudoscalar boson pairs produced from decays of the 125 GeV Higgs boson in final states with two muons and two nearby tracks in pp collisions at s=13TeV
(2020)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsA search is presented for pairs of light pseudoscalar bosons, in the mass range from 4 to 15 GeV, produced from decays of the 125 GeV Higgs boson. The decay modes considered are final states that arise when one of the pseudoscalars decays to a pair of tau leptons, and the other one either into a pair of tau leptons or muons. The search is based on proton-proton collisions collected by the CMS experiment in 2016 at a center-of-mass energy ...Journal Article -
Measurement of the single top quark and antiquark production cross sections in the t channel and their ratio in proton-proton collisions at s=13TeV
(2020)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsMeasurements of the cross sections for the production of single top quarks and antiquarks in the t channel, and their ratio, are presented for proton-proton collisions at a center-of-mass energy of 13 TeV. The data set used was recorded in 2016 by the CMS detector at the LHC and corresponds to an integrated luminosity of 35.9 fb−1. Events with one muon or electron are selected, and different categories of jet and b jet multiplicity and ...Journal Article -
Observation of nuclear modifications in W± production in pPb collisions at sNN=8.16TeV
(2020)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsThe production of W± bosons is studied in proton-lead (pPb) collisions at a nucleon-nucleon centre-of-mass energy of sNN=8.16TeV. Measurements are performed in the W±→μ±νμ channel using a data sample corresponding to an integrated luminosity of 173.4±6.1nb−1, collected by the CMS Collaboration at the LHC. The number of positively and negatively charged W bosons is determined separately in the muon pseudorapidity region in the laboratory ...Journal Article -
Measurement of t t ¯ normalised multi-differential cross sections in pp collisions at √s=13TeV , and simultaneous determination of the strong coupling strength, top quark pole mass, and parton distribution functions
(2020)The European Physical Journal CNormalised multi-differential cross sections for top quark pair (t t ¯) production are measured in proton-proton collisions at a centre-of-mass energy of 13TeV using events containing two oppositely charged leptons.
