Observation of Forward Neutron Multiplicity Dependence of Dimuon Acoplanarity in Ultraperipheral Pb-Pb Collisions at sNN =5.02 TeV
(American Physical Society, 2021)
The first measurement of the dependence of γγ→μ+μ- production on the multiplicity of neutrons emitted very close to the beam direction in ultraperipheral heavy ion collisions is reported. Data for lead-lead interactions ...
Strategies and performance of the CMS silicon tracker alignment during LHC Run 2
(Elsevier, 2022)
The strategies for and the performance of the CMS silicon tracking system alignment during the 2015–2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. ...
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 ...
