Search for long-lived heavy neutral leptons with displaced vertices in proton-proton collisions at root s=13 TeV
(Springer, 2022)
A search for heavy neutral leptons (HNLs), the right-handed Dirac or Majorana neutrinos, is performed in final states with three charged leptons (electrons or muons) using proton-proton collision data collected by the CMS ...
Measurement of the Drell-Yan forward-backward asymmetry at high dilepton masses in proton-proton collisions at root s=13 TeV
(Springer, 2022)
A measurement of the forward-backward asymmetry of pairs of oppositely charged leptons (dimuons and dielectrons) produced by the Drell-Yan process in proton-proton collisions is presented. The data sample corresponds to ...
Measurement of the Higgs boson width and evidence of its off-shell contributions to ZZ production
(Nature Research, 2022)
Since the discovery of the Higgs boson in 2012, detailed studies of its properties have been ongoing. Besides its mass, its width—related to its lifetime—is an important parameter. One way to determine this quantity is to ...
Search for long-lived particles decaying to leptons with large impact parameter in proton-proton collisions at root s=13 TeV
(Springer, 2022)
A search for new long-lived particles decaying to leptons using proton-proton collision data produced by the CERN LHC at root s = 13 TeV is presented. Events are selected with two leptons (an electron and a muon, two ...
Probing Charm Quark Dynamics via Multiparticle Correlations in Pb-Pb Collisions at root s(NN)=5.02 TeV
(American Physical Society, 2022)
Multiparticle azimuthal correlations of prompt D-0 mesons arc measured in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of root s(NN) = 5.02 TeV. For the first time, a four-particle cumulant method is used ...
Search for charged-lepton flavor violation in top quark production and decay in pp collisions at root s=13 TeV
(Springer, 2022)
Results are presented from a search for charged-lepton flavor violating (CLFV) interactions in top quark production and decay in pp collisions at a center-of-mass energy of 13 TeV. The events are required to contain one ...
Search for a right-handed W boson and a heavy neutrino in proton-proton collisions at root s=13 TeV
(Springer, 2022)
A search is presented for a right-handed W boson (W-R) and a heavy neutrino (N), in a final state consisting of two same-flavor leptons (ee or mu mu) and two quarks. The search is performed with the CMS experiment at the ...
Observation of B 0 → ψ (2S)K 0 S π + π − and B 0 s → ψ (2S)K 0 S decays
(Springer, 2022)
t Using a data sample of √s = 13 TeV protonproton collisions collected by the CMS experiment at
the LHC in 2017 and 2018 with an integrated luminosity of 103 fb−1, the B0s → ψ(2S)K0S and B0 →ψ(2S)K0Sπ+π− decays are observed ...
Search for electroweak production of charginos and neutralinos in proton-proton collisions at √s = 13 TeV
(Springer, 2022)
A direct search for electroweak production of charginos and neutralinos is presented. Events with three or four leptons, with up to two hadronically decaying τ leptons, or two same-sign light leptons are analyzed. The data ...
Search for higgsinos decaying to two Higgs bosons and missing transverse momentum in proton-proton collisions at root s=13 TeV
(Springer, 2022)
Results are presented from a search for physics beyond the standard model in proton-proton collisions at root s = 13 TeV in channels with two Higgs bosons, each decaying via the process H -> b (b) over bar, and large missing ...
