Development and validation of HERWIG 7 tunes from CMS underlying-event measurements
(Springer, 2021-04-12)
This paper presents new sets of parameters (“tunes”) for the underlying-event model of the HERWIG7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in ...
Search for singly and pair-produced leptoquarks coupling to third-generation fermions in proton-proton collisions at √s = 13 TeV
(Elsevier, 2021-08-10)
A search for leptoquarks produced singly and in pairs in proton-proton collisions is presented. We consider the leptoquark (LQ) to be a scalar particle of charge −1/3e coupling to a top quark plus a tau lepton (tτ) or a ...
Measurement of differential cross sections for Z boson pair production in association with jets at √s=8 and 13 TeV
(Elsevier, 2019-02-10)
This Letter reports measurements of differential cross sections for the production of two Z bosons in association with jets in proton-proton collisions at root s = 8 and 13 TeV. The analysis is based on data samples collected ...
Search for the rare decay of the W boson into a pion and a photon in proton-proton collisions at √s = 13 TeV
(Elsevier, 2021-08-10)
A search is performed for the rare decay W±→π±γ in proton-proton collisions at s=13TeV. Data corresponding to an integrated luminosity of 137fb−1 were collected during 2016 to 2018 with the CMS detector. This analysis ...
Measurement of the azimuthal anisotropy of Υ(1S) and Υ(2S) mesons in PbPb collisions at √sNN = 5.02 TeV
(Elsevier, 2021-08-10)
The second-order Fourier coefficients (v2) characterizing the azimuthal distributions of [Formula presented] and [Formula presented] mesons produced in PbPb collisions at s =5.02TeV are studied. The [Formula presented] ...
Observation of the Λb 0→J/ψΛϕ decay in proton-proton collisions at √s=13 TeV
(Elsevier, 2020-03-10)
The observation of the Lambda(0)(b) -> J/psi Lambda phi decay is reported using proton-proton collision data collected at root s = 13TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity ...
Measurement of the Higgs boson production rate in association with top quarks in final states with electrons, muons, and hadronically decaying tau leptons at s√=13 TeV
(Springer, 2021-04-30)
The rate for Higgs (H) bosons production in association with either one (t H) or two (t t ¯ H) top quarks is measured in final states containing multiple electrons, muons, or tau leptons decaying to hadrons and a neutrino, ...
Search for W′ bosons decaying to a top and a bottom quark at √s = 13 TeV in the hadronic final state
(Elsevier, 2021-09-10)
A search is performed for W′ bosons decaying to a top and a bottom quark in the all-hadronic final state, in proton-proton collisions at a center-of-mass energy of 13 TeV. The analyzed data were collected by the CMS ...
The very forward CASTOR calorimeter of the CMS experiment
(IOP Publishing, 2021-02-08)
The physics motivation, detector design, triggers, calibration, alignment, simulation, and overall performance of the very forward CASTOR calorimeter of the CMS experiment are reviewed. The CASTOR Cherenkov sampling ...
Inclusive search for supersymmetry in pp collisions at s√ = 13 TeV using razor variables and boosted object identification in zero and one lepton final states
(Springer Nature, 2019-03-06)
An inclusive search for supersymmetry (SUSY) using the razor variables is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 35.9 fb(-1), collected with the CMS experiment ...
