Bose-Einstein Correlations in pp, pPb, and PbPb Collisions at √sNN = 0.9 – 7 TeV
(American Physical Society, 2018-06)
Quantum-statistical (Bose-Einstein) two-particle correlations are measured in pp collisions at √s =0.9, 2.76, and 7 TeV, as well as in pPb and peripheral PbPb collisions at nucleon-nucleon center-of-mass energies of 5.02 ...
Search for New Phenomena with Multiple Charged Leptons in Proton–proton Collisions at √s = 13 TeV
(Springer Berlin Heidelberg, 2017-09)
Results are reported from a search for physics beyond the standard model in final states with at least three charged leptons, in any combination of electrons or muons. The data sample corresponds to an integrated luminosity ...
Measurement of the sum of WW and WZ production with W+dijet events in pp collisions at √s = 7 TeV
(Springer-Verlag, 2013-02)
A measurement of the inclusive WW+WZ diboson production cross section in proton–proton collisions is reported, based on events containing a leptonically decaying W boson and exactly two jets. The data sample, collected at ...
Search for Resonant Production of High-Mass Photon Pairs in Proton-Proton Collisions at √s=8 and 13 TeV
(American Physical Society, 2016-07)
A search for the resonant production of high-mass photon pairs is presented. The analysis is based on samples of proton-proton collision data collected by the CMS experiment at center-of-mass energies of 8
and 13 TeV, ...
Study of high-p T charged particle suppression in PbPb compared to pp collisions at √sNN = 2.76 TeV
(Elsevier, 2012-03)
The transverse momentum spectra of charged particles have been measured in pp and PbPb collisions at √sNN=2.76 TeV by the CMS experiment at the LHC. In the transverse momentum range pT=5–10 GeV/c, the charged particle yield ...
Search for Top Quark Decays via Higgs-Boson-Mediated Flavor-Changing Neutral Currents in Pp Collisions at √s = 8 TeV
(Springer Nature, 2017-07)
A search is performed for Higgs-boson-mediated flavor-changing neutral currents in the decays of top quarks. The search is based on proton-proton collision data corresponding to an integrated luminosity of 19.7 fb⁻¹ at a ...
Forward–backward asymmetry of Drell–Yan lepton pairs in pp collisions at √s = 7 TeV
(Elsevier, 2012-11)
A measurement of the forward–backward asymmetry (A[subscript FB]) of Drell–Yan lepton pairs in pp collisions at √s = 7 TeV is presented. The data sample, collected with the CMS detector, corresponds to an integrated ...
Search for a pseudoscalar boson decaying into a Z boson and the 125 GeV Higgs boson in ℓ[superscript +]ℓ[superscript −]b[bar over b] final states
(Elsevier, 2015-07)
Results are reported on a search for decays of a pseudoscalar A boson into a Z boson and a light scalar h boson, where the Z boson decays into a pair of oppositely-charged electrons or muons, and the h boson decays into ...
Studies of B∗s2(5840)⁰ and Bs1(5830)⁰ mesons including the observation of the B∗s2(5840)⁰ → B⁰K⁰ S decay in proton-proton collisions at √s = 8 TeV
(Springer, 2018-11)
Measurements of B[superscript * over subscript s2](5840)⁰ and B[subscript s1](5830)⁰ mesons are performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 19.6 fb-¹, collected ...
Mechanical stability of the CMS strip tracker measured with a laser alignment system
(IOP Publishing, 2017-04)
The CMS tracker consists of 206 m 2 of silicon strip sensors assembled on carbon fibre composite structures and is designed for operation in the temperature range from -25 to +25°C. The mechanical stability of tracker ...
