Measurement of the double-differential inclusive jet cross section in proton-proton collisions at s = 5.02 TeV

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

The inclusive jet cross section is measured as a function of jet transverse momentum pT and rapidity y. The measurement is performed using proton-proton collision data at s = 5.02 TeV, recorded by the CMS experiment at the LHC, corresponding to an integrat ...

Measurement of the inclusive WZ production cross section in pp collisions at s = 13.6 TeV

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

The inclusive WZ production cross section is measured in proton-proton collisions at a centre-of-mass energy of 13.6 TeV, using data collected during 2022 with the CMS detector, corresponding to an integrated luminosity of 34.7 fb−1. The measurement uses m ...

Search for bosons of an extended Higgs sector in b quark final states in proton-proton collisions at s = 13 TeV

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

A search for beyond-the-standard-model neutral Higgs bosons decaying to a pair of bottom quarks, and produced in association with at least one additional bottom quark, is performed with the CMS detector. The data were recorded in proton-proton collisions a ...

Searches for violation of Lorentz invariance in top quark pair production using dilepton events in 13 TeV proton-proton collisions

Joanna Malgorzata Wanczyk

A search for violation of Lorentz invariance in the production of top quark pairs (t (t) over bar) is presented. The measured normalized differential t (t) over bar production cross section, as a function of the sidereal time, is examined for potential mod ...

Search for supersymmetry in final states with disappearing tracks in proton-proton collisions at √s=13 TeV

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

A search is presented for charged, long-lived supersymmetric particles in final states with one or more disappearing tracks. The search is based on data from proton-proton collisions at a center-of-mass energy of 13 TeV collected with the CMS detector at t ...

Search for the Z Boson Decay to ττμμ in Proton-Proton Collisions at √s=13 TeV

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

The first search for the Z boson decay to tau tau mu mu at the CERN LHC is presented, based on data collected by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of ...

Combined search for electroweak production of winos, binos, higgsinos, and sleptons in proton-proton collisions at √s=13 TeV

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

A combination of the results of several searches for the electroweak production of the supersymmetric partners of standard model bosons, and of charged leptons, is presented. All searches use proton-proton collision data at root s = 13 TeV recorded with th ...

Observation of double J/ψ meson production in pPb collisions at √sNN=8.16 TeV

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

The first observation of the concurrent production of two J/psi mesons in proton-nucleus collisions is presented. The analysis is based on a proton-lead (pPb) data sample recorded at a nucleon-nucleon center-of-mass energy of 8.16 TeV by the CMS experiment ...

Search for long-lived heavy neutral leptons with lepton flavour conserving or violating decays to a jet and a charged lepton

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

A search for long-lived heavy neutral leptons (HNLs) is presented, which considers the hadronic final state and coupling scenarios involving all three lepton generations in the 2-20 GeV HNL mass range for the first time. Events comprising two leptons (elec ...

Search for central exclusive production of top quark pairs in proton-proton collisions at √s=13 TeV with tagged protons

Konstantin Androsov, Jan Steggemann, Anna Mascellani, Joanna Malgorzata Wanczyk

A search for the central exclusive production of top quark-antiquark pairs (t (t) over bar) is performed for the first time using proton-tagged events in proton-proton collisions at the LHC at a centre-of-mass energy of 13TeV. The data correspond to an int ...
