Measurement of the cross section for t t ¯ production with additional jets and b jets in pp collisions at √s = 13 TeV
(2020)Journal of High Energy PhysicsMeasurements of the cross section for the production of top quark pairs in association with a pair of jets from bottom quarks (σtt¯bb¯¯¯) and in association with a pair of jets from quarks of any flavor or gluons (σtt¯jj) and their ratio are presented. The data were collected in proton-proton collisions at a center-of-mass energy of 13 TeV by the CMS experiment at the LHC in 2016 and correspond to an integrated luminosity of 35.9 fb−1. ...Journal Article -
Combination of the W boson polarization measurements in top quark decays using ATLAS and CMS data at √s = 8 TeV
(2020)Journal of High Energy PhysicsThe combination of measurements of the W boson polarization in top quark decays performed by the ATLAS and CMS collaborations is presented. The measurements are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 8 TeV, and corresponding to an integrated luminosity of about 20 fb−1 for each experiment. The measurements used events containing one lepton and having different jet multiplicities in the final ...Journal Article -
First measurement of the forward rapidity gap distribution in pPb collisions at √sNN = 8.16 TeV
(2023)Physical Review DFor the first time at LHC energies, the forward rapidity gap spectra from proton-lead collisions for both proton and lead dissociation processes are presented. The analysis is performed over 10.4 units of pseudorapidity at a center-of-mass energy per nucleon pair of √sNN = 8.16 TeV, almost 300 times higher than in previous measurements of diffractive production in proton-nucleus collisions. For lead dissociation processes, which correspond ...Journal Article -
Measurement of the mass dependence of the transverse momentum of lepton pairs in Drell–Yan production in proton–proton collisions at √s=13TeV
(2023)The European Physical Journal CThe double differential cross sections of the Drell–Yan lepton pair (ℓ+ℓ- , dielectron or dimuon) production are measured as functions of the invariant mass mℓℓ , transverse momentum pT(ℓℓ) , and φη∗ . The φη∗ observable, derived from angular measurements of the leptons and highly correlated with pT(ℓℓ) , is used to probe the low- pT(ℓℓ) region in a complementary way. Dilepton masses up to 1 TeV are investigated. Additionally, a measurement ...Journal Article -
Azimuthal Correlations within Exclusive Dijets with Large Momentum Transfer in Photon-Lead Collisions
(2023)Physical Review LettersThe structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. The first measurement of the azimuthal angular correlations of exclusively produced events with two jets in photon-lead interactions at large momentum transfer is presented, a process ...Journal Article -

Search for resonances in events with photon and jet final states in proton-proton collisions at √s = 13 TeV
(2023)Journal of High Energy PhysicsA search for resonances in events with the γ+jet final state has been performed using proton-proton collision data collected at √s = 13 TeV by the CMS experiment at the LHC. The total data analyzed correspond to an integrated luminosity of 138 fb−1. Models of excited quarks and quantum black holes are considered. Using a wide-jet reconstruction for the candidate jet, the γ+jet invariant mass spectrum measured in data is examined for the ...Journal Article -
Search for Scalar Leptoquarks Produced via τ -Lepton–Quark Scattering in pp Collisions at √s = 13 TeV
(2024)Physical Review LettersThe first search for scalar leptoquarks produced in τ-lepton–quark collisions is presented. It is based on a set of proton-proton collision data recorded with the CMS detector at the LHC at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 138 fb⁻¹. The reconstructed final state consists of a jet, significant missing transverse momentum, and a τ lepton reconstructed through its hadronic or leptonic decays. ...Journal Article
