Search for CP violating top quark couplings in pp collisions at √s = 13 TeV
(2023)Journal of High Energy PhysicsResults are presented from a search for CP violation in top quark pair production, using proton-proton collisions at a center-of-mass energy of 13 TeV. The data used for this analysis consist of final states with two charged leptons collected by the CMS experiment, and correspond to an integrated luminosity of 35.9 fb−1. The search uses two observables, O1 and O3, which are Lorentz scalars. The observable O1 is constructed from the ...Journal Article -
Measurements of jet multiplicity and jet transverse momentum in multijet events in proton–proton collisions at √s=13TeV
(2023)The European Physical Journal CMultijet events at large transverse momentum (p_T) are measured at s√=13TeV using data recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of 36.3fb⁻¹. The multiplicity of jets with p_T>50GeV that are produced in association with a high-p_T dijet system is measured in various ranges of the p_T of the jet with the highest transverse momentum and as a function of the azimuthal angle difference Δϕ_1,2 between ...Journal Article -

First measurement of the top quark pair production cross section in proton-proton collisions at √s = 13.6 TeV
(2023)Journal of High Energy PhysicsThe first measurement of the top quark pair (tt¯) production cross section in proton-proton collisions at √s = 13.6 TeV is presented. Data recorded with the CMS detector at the CERN LHC in Summer 2022, corresponding to an integrated luminosity of 1.21 fb⁻¹, are analyzed. Events are selected with one or two charged leptons (electrons or muons) and additional jets. A maximum likelihood fit is performed in event categories defined by the ...Journal Article -
