A search for new physics in central exclusive production using the missing mass technique with the CMS detector and the CMS-TOTEM precision proton spectrometer
(2023)The European Physical Journal CA generic search is presented for the associated production of a Z boson or a photon with an additional unspecified massive particle X, pp → pp + Z / γ + X , in proton-tagged events from proton–proton collisions at √s=13TeV , recorded in 2017 with the CMS detector and the CMS-TOTEM precision proton spectrometer. The missing mass spectrum is analysed in the 600–1600 GeV range and a fit is performed to search for possible deviations from ...Journal Article -
Evidence for four-top quark production in proton-proton collisions at √s=13TeV
(2023)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsThe production of four top quarks (tt‾tt‾) is studied with LHC proton-proton collision data samples collected by the CMS experiment at a center-of-mass energy of 13 TeV, and corresponding to integrated luminosities of up to 138fb⁻¹. Events that have no leptons (all-hadronic), one lepton, or two opposite-sign leptons (where lepton refers only to prompt electrons or prompt muons) are considered. This is the first tt‾tt‾ measurement that ...Journal Article -

Search for Higgs Boson Decay to a Charm Quark-Antiquark Pair in Proton-Proton Collisions at √ s = 13 TeV
(2023)Physical Review LettersA search for the standard model Higgs boson decaying to a charm quark-antiquark pair, H → cc¯, produced in association with a leptonically decaying V (W or Z) boson is presented. The search is performed with proton-proton collisions at √ s = 13 TeV collected by the CMS experiment, corresponding to an integrated luminosity of 138 fb⁻¹. Novel charm jet identification and analysis methods using machine learning techniques are employed. The ...Journal Article -

Measurement of the top quark pole mass using t (t)over-bar+jet events in the dilepton final state in proton-proton collisions at â s=13 TeV
(2023)Journal of High Energy PhysicsA measurement of the top quark pole mass m(t)(pole) in events where a top quarkantiquark pair (t (t) over bar) is produced in association with at least one additional jet ( t (t) over bar +jet) is presented. This analysis is performed using proton-proton collision data at root s = 13TeV collected by the CMS experiment at the CERN LHC, corresponding to a total integrated luminosity of 36.3 fb(-1). Events with two opposite-sign leptons in ...Journal Article -
Probing Heavy Majorana Neutrinos and the Weinberg Operator through Vector Boson Fusion Processes in Proton-Proton Collisions at √s=13 TeV
(2023)Physical Review LettersThe first search exploiting the vector boson fusion process to probe heavy Majorana neutrinos and the Weinberg operator at the LHC is presented. The search is performed in the same-sign dimuon final state using a proton-proton collision dataset recorded at √s=13 TeV, collected with the CMS detector and corresponding to a total integrated luminosity of 138 fb−1. The results are found to agree with the predictions of the standard model. ...Journal Article
