Search for physics beyond the standard model in multilepton final states in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
A search for physics beyond the standard model in events with at least three charged leptons (electrons or muons) is presented. The data sample corresponds to an integrated luminosity of 137 fb−1 of proton-proton collisions ...
Measurement of the cross section for t t ¯ production with additional jets and b jets in pp collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
Measurements of the cross section for the production of top quark pairs in association with a pair of jets from bottom quarks (σtt ¯bb ¯) and in association with a pair of jets from quarks of any flavor or gluons (σtt ¯jj) ...
Search for dark photons in Higgs boson production via vector boson fusion in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2021)
A search is presented for a Higgs boson that is produced via vector boson fusion and that decays to an undetected particle and an isolated photon. The search is performed by the CMS collaboration at the LHC, using a data ...
Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected ...
Measurement of quark- and gluon-like jet fractions using jet charge in PbPb and pp collisions at 5.02 TeV
(Journal of High Energy Physics, 2020)
The momentum-weighted sum of the electric charges of particles inside a jet, known as jet charge, is sensitive to the electric charge of the particle initiating the parton shower. This paper presents jet charge distributions ...
Search for contact interactions and large extra dimensions in the dilepton mass spectra from proton-proton collisions at √s=13 TeV
(Journal of High Energy Physics, 2019)
A search for nonresonant excesses in the invariant mass spectra of electron and muon pairs is presented. The analysis is based on data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the CMS ...
A search for the standard model Higgs boson decaying to charm quarks
(Journal of High Energy Physics, 2020)
A direct search for the standard model Higgs boson, H, produced in association with a vector boson, V (W or Z), and decaying to a charm quark pair is presented. The search uses a data set of proton-proton collisions ...
Search for a heavy pseudoscalar Higgs boson decaying into a 125 GeV Higgs boson and a Z boson in final states with two tau and two light leptons at √s = 13 TeV
(Journal of High Energy Physics, 2020)
A search is performed for a pseudoscalar Higgs boson, A, decaying into a 125 GeV Higgs boson h and a Z boson. The h boson is specifically targeted in its decay into a pair of tau leptons, while the Z boson decays into a ...
Search for a heavy Higgs boson decaying to a pair of W bosons in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
A search for a heavy Higgs boson in the mass range from 0.2 to 3.0 TeV, decaying to a pair of W bosons, is presented. The analysis is based on proton-proton collisions at s = 13 TeV recorded by the CMS experiment at the ...
Bose-Einstein correlations of charged hadrons in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at s = 13 TeV. The results are based ...
