Alignment of the CMS silicon tracker during commissioning with cosmic rays
(IOP Publishing, 2010-03)
The CMS silicon tracker, consisting of 1440 silicon pixel and 15 148 silicon strip detector modules, has been aligned using more than three million cosmic ray charged particles, with additional information from optical ...
Commissioning of the CMS High-Level Trigger with cosmic rays
(2010-03)
The CMS High-Level Trigger (HLT) is responsible for ensuring that data samples with potentially interesting events are recorded with high efficiency and good quality. This paper gives an overview of the HLT and focuses on ...
Measurement of the muon stopping power in lead tungstate
(IOP Publishing, 2010-03)
A large sample of cosmic ray events collected by the CMS detector is exploited to measure the specific energy loss of muons in the lead tungstate (PbWO₄) of the electromagnetic calorimeter. The measurement spans a momentum ...
Search for R-Parity Violating Supersymmetry in Pp Collisions at √s=13 TeV using b Jets in a Final State with a Single Lepton, Many Jets, and High Sum of Large-Radius Jet Masses
(Elsevier, 2018-06)
Results are reported from a search for physics beyond the standard model in proton–proton collisions at a center-of-mass energy of √s=13 TeV. The search uses a signature of a single lepton, large jet and bottom quark jet ...
Search for dark matter and unparticles in events with a Z boson and missing transverse momentum in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2017-03)
A search for dark matter and unparticle production at the LHC has been performed using events containing two charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum. ...
Measurement of Jet Substructure Observables in tt¯Events from Proton-Proton Collisions at √s = 13 TeV
(American Institute of Physics (AIP), 2018-11)
A measurement of jet substructure observables is presented using t¯t events in the lepton+jets channel from proton-proton collisions at √s=13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated ...
Search for Additional Neutral MSSM Higgs Bosons in the τ τ Final State in Proton-Proton Collisions at √s = 13 TeV
(Springer Nature, 2018-09)
A search is presented for additional neutral Higgs bosons in the τ τ final state in proton-proton collisions at the LHC. The search is performed in the context of the minimal supersymmetric extension of the standard model ...
Search for Heavy Resonances Decaying to Tau Lepton Pairs in Proton-Proton Collisions at √s = 13 TeV
(Springer Nature, 2017-02)
A search for heavy resonances that decay to tau lepton pairs is performed using proton-proton collisions at √s = 13 TeV. The data were collected with the CMS detector at the CERN LHC and correspond to an integrated luminosity ...
Alignment of the CMS muon system with cosmic-ray and beam-halo muons
(IOP Publishing, 2010-03)
The CMS muon system has been aligned using cosmic-ray muons collected in 2008 and beam-halo muons from the 2008 LHC circulating beam tests. After alignment, the resolution of the most sensitive coordinate is 80 microns for ...
Measurements of Higgs Boson Properties in the Diphoton Decay Channel in Proton-Proton Collisions at √s =13 TeV
(Springer, 2018-11)
Measurements of Higgs boson properties in the H → γγ decay channel are reported. The analysis is based on data collected by the CMS experiment in proton-proton collisions at √s = 13 TeV during the 2016 LHC running period, ...
