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 -
Measurements of the azimuthal anisotropy of prompt and nonprompt charmonia in PbPb collisions at √sNN = 5.02 TeV
(2023)Journal of High Energy PhysicsThe second-order (v2) and third-order (v3) Fourier coefficients describing the azimuthal anisotropy of prompt and nonprompt (from b-hadron decays) J/ψ, as well as prompt ψ(2S) mesons are measured in lead-lead collisions at a center-of-mass energy per nucleon pair of √sNN = 5.02 TeV. The analysis uses a data set corresponding to an integrated luminosity of 1.61 nb−1 recorded with the CMS detector. The J/ψ and ψ(2S) mesons are reconstructed ...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 -
Measurement of the cross section of top quark-antiquark pair production in association with a W boson in proton-proton collisions at √s = 13 TeV
(2023)Journal of High Energy PhysicsThe production of a top quark-antiquark pair in association with a W boson (t (t) over barW) is measured in proton-proton collisions at a center-of-mass energy of 13TeV. The analyzed data was recorded by the CMS experiment at the CERN LHC and corresponds to an integrated luminosity of 138 fb(-1). Events with two or three leptons (electrons and muons) and additional jets are selected. In events with two leptons, a multiclass neural network ...Journal Article -
Measurement of the Higgs boson inclusive and differential fiducial production cross sections in the diphoton decay channel with pp collisions at √s = 13 TeV
(2023)Journal of High Energy PhysicsThe measurements of the inclusive and differential fiducial cross sections of the Higgs boson decaying to a pair of photons are presented. The analysis is performed using proton-proton collisions data recorded with the CMS detector at the LHC at a centre-of-mass energy of 13TeV and corresponding to an integrated luminosity of 137 fb(-1). The inclusive fiducial cross section is measured to be sigma(fid) = 73.4(-5.3)(+5.4)(stat)(+2.4)(-2.2)(syst) ...Journal Article -
Measurement of inclusive and differential cross sections for single top quark production in association with a W boson in proton-proton collisions at √s = 13 TeV
(2023)Journal of High Energy PhysicsMeasurements of the inclusive and normalised differential cross sections are presented for the production of single top quarks in association with a W boson in proton-proton collisions at a centre-of-mass energy of 13 TeV. The data used were recorded with the CMS detector at the LHC during 2016–2018, and correspond to an integrated luminosity of 138 fb⁻¹. Events containing one electron and one muon in the final state are analysed. For the ...Journal Article -

Search for neutral MSSM Higgs bosons at LEP
(2006)The European Physical Journal CThe four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric standard model (MSSM). The data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and with a possible Higgs boson signal. The combined LEP data show no significant excess of events which would indicate the production of ...Journal Article
