Measurements of tt¯ spin correlations and top quark polarization using dilepton final states in pp collisions at s√=8 TeV
(American Physical Society, 2016-03)
Measurements of the top quark-antiquark (t¯t) spin correlations and the top quark polarization are presented for t¯t pairs produced in pp collisions at √s=8 TeV. The data correspond to an integrated luminosity of 19.5 fb⁻¹ ...
Measurement of prompt and nonprompt charmonium suppression in PbPb collisions at 5.02 TeV
(Springer Berlin Heidelberg, 2018-06)
The nuclear modification factors of J/ψ and ψ (2S) mesons are measured in PbPb collisions at a centre-of-mass energy per nucleon pair of √s[subscript NN] = 5.02 TeV. The analysis is based on PbPb
and pp data samples ...
Event Shapes and Azimuthal Correlations in Z+jets Events in Pp Collisions at √S=7 TeV
(Elsevier BV, 2013-05)
Measurements of event shapes and azimuthal correlations are presented for events where a Z boson is produced in association with jets in proton-proton collisions. The data collected with the CMS detector at the CERN LHC ...
Measurement of the ratio of the inclusive 3-jet cross section to the inclusive 2-jet cross section in pp collisions at √s = 7 TeV and first determination of the strong coupling constant in the TeV range
(Springer-Verlag, 2013-10)
A measurement is presented of the ratio of the inclusive 3-jet cross section to the inclusive 2-jet cross section as a function of the average transverse momentum, ⟨p[subscript T1,2]⟩, of the two leading jets in the event. ...
Prompt and non-prompt J/ψ production in pp collisions at √s = 7 TeV
(Springer Nature, 2011-03)
The production of J/ψ mesons is studied in pp collisions at √s = 7 TeV with the CMS experiment at the LHC. The measurement is based on a dimuon sample corresponding to an integrated luminosity of 314 nb[superscript -1]. ...
Search for New Physics in Events with Two Soft Oppositely Charged Leptons and Missing Transverse Momentum in Proton–proton Collisions at √s = 13 TeV
(Elsevier, 2018-05)
A search is presented for new physics in events with two low-momentum, oppositely charged leptons (electrons or muons) and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 13 TeV. The ...
Search for neutral color-octet weak-triplet scalar particles in proton-proton collisions at √ s = 8 TeV
(Springer-Verlag/SISSA, 2015-09)
A search for pair production of neutral color-octet weak-triplet scalar particles (Θ[superscript 0]) is performed in processes where one Θ[superscript 0] decays to a pair of b quark jets and the other to a Z boson plus a ...
Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at √s = 13 TeV
(Springer International Publishing AG, 2018-04-12)
A search for narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in proton-proton collisions at s√=13 TeV with the CMS detector at the LHC, corresponding to ...
Search for fractionally charged particles in pp collisions at √s=7 TeV
(American Physical Society, 2013-05)
A search is presented for free heavy long-lived fractionally charged particles produced in pp collisions at √s=7 TeV. The data sample was recorded by the CMS detector at the LHC and corresponds to an integrated luminosity ...
A search for excited leptons in pp collisions at √s = 7 TeV
(Elsevier, 2011-09)
A search for excited leptons is carried out with the CMS detector at the LHC, using 36 pb[superscript −1] of pp collision data recorded at √s = 7 TeV. The search is performed for associated production of a lepton and an ...
