Search for dark matter particles produced in association with a Higgs boson in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
A search for dark matter (DM) particles is performed using events with a Higgs boson candidate and large missing transverse momentum. The analysis is based on proton- proton collision data at a center-of-mass energy of 13 ...
Search for top squark pair production in a final state with two tau leptons in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
A search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at s $$ \sqrt{s} $$ = 13 TeV is presented in a final state containing hadronically ...
Search for charged Higgs bosons decaying into a top and a bottom quark in the all-jet final state of pp collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
A search for charged Higgs bosons (H±) decaying into a top and a bottom quark in the all-jet final state is presented. The analysis uses LHC proton-proton collision data recorded with the CMS detector in 2016 at s = 13 ...
Search for an excited lepton that decays via a contact interaction to a lepton and two jets in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
Results are presented from a search for events containing an excited lepton (electron or muon) produced in association with an ordinary lepton of the same flavor and decaying to a lepton and two hadronic jets. Both the ...
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) ...
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 ...
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 ...
