A new calibration method for charm jet identification validated with proton-proton collision events at root s=13 TeV
(Springer, 2022)
Many measurements at the LHC require efficient identification of heavy-flavour jets, i.e. jets originating from bottom (b) or charm (c) quarks. An overview of the algorithms used to identify c jets is described and a novel ...
Performance of the CMS muon trigger system in proton-proton collisions at root s=13 TeV
(IOP Publishing, 2022)
The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015-2018) the LHC achieved instantaneous luminosities as high as 2 x ...
Search for Resonances Decaying to Three W Bosons in Proton-Proton Collisions at ps=13 TeV
(American Physical Society, 2022)
A search for resonances decaying into a W boson and a radion, where the radion decays into two W bosons, is presented. The data analyzed correspond to an integrated luminosity of 138 fb???1 recorded in ffiffiproton-proton ...
Measurement of prompt and nonprompt charmonium suppression in PbPb collisions at 5.02 TeV
(Institute for Ionics, 2018)
The nuclear modification factors of J/psi and psi(2S) mesons are measured in PbPb collisions at a centre-of-mass energy per nucleon pair of root S-NN = 5.02 TeV. The analysis is based on PbPb and pp data samples collected ...
Measurements of the associated production of a W boson and a charm quark in proton-proton collisions at √ s = 8 TeV
(SpringerOpen, 2022)
Measurements of the associated production of a W boson and a charm (c) quark in proton–proton collisions at a centre-of-mass energy of 8TeV are reported. The analysis uses a data sample corresponding to a total integrated ...
Measurement of the inclusive and differential WZ production cross sections, polarization angles, and triple gauge couplings in pp collisions at root s=13 TeV
(Springer, 2022)
The associated production of a W and a Z boson is studied in final states with multiple leptons produced in proton-proton (pp) collisions at a centre-of-mass energy of 13 TeV using 137 fb(-1) of data collected with the CMS ...
Identification of hadronic tau lepton decays using a deep neural network
(IOP Publishing, 2022)
new algorithm is presented to discriminate reconstructed hadronic decays of tau leptons (τ h) that originate from genuine tau leptons in the CMS detector against τ h candidates that originate from quark or gluon jets, ...
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 ...
