Exclusive γγ → μ⁺μ⁻ production in proton-proton collisions at √s = 7 TeV
(Springer Berlin Heidelberg, 2012-01)
A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at √s = 7 TeV, pp → pμ⁺μ⁻ p, is reported using data corresponding to an integrated luminosity of 40 pb⁻¹. For muon pairs with ...
CMS tracking performance results from early LHC operation
(Springer-Verlag, 2010-11)
The first LHC pp collisions at centre-of-mass energies of 0.9 and 2.36 TeV were recorded by the CMS detector in December 2009. The trajectories of charged particles produced in the collisions were reconstructed using the ...
Measurement of Quarkonium Production Cross Sections in Pp Collisions at √s = 13 TeV
(Elsevier, 2018-03)
Differential production cross sections of prompt J/ψ and ψ(2S) charmonium and ϒ(nS) (n=1,2,3) bottomonium states are measured in proton–proton collisions at √s = 13 TeV, with data collected by the CMS detector at the LHC, ...
Search for Top Squarks Decaying via Four-Body or Chargino-Mediated Modes in Single-Lepton Final States in Proton-Proton Collisions at √s = 13 TeV
(Springer Nature, 2018-09)
A search for the pair production of the lightest supersymmetric partner of the top quark (t~[subscript 1]) is presented. The search focuses on a compressed scenario where the mass difference between the top squark and the ...
Search for supersymmetry in pp collisions at √s=7 TeV in events with a single lepton, jets, and missing transverse momentum
(Springer-Verlag, 2013-05)
Results are reported from a search for new physics processes in events containing a single isolated high-transverse-momentum lepton (electron or muon), energetic jets, and large missing transverse momentum. The analysis ...
Measurement of the t[bar over t] production cross section in the τ+jets channel in pp collisions at √s =7 TeV
(Springer-Verlag, 2013-04)
The top-quark pair production cross section in 7 TeV center-of-mass energy proton–proton collisions is measured using data collected by the CMS detector at the LHC. The measurement uses events with one jet identified
as ...
Search for anomalous production of multilepton events in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-06)
A search for anomalous production of events with three or more isolated leptons in pp collisions at √s = 7 TeV is presented. The data, corresponding to an integrated luminosity of 4.98 fb[superscript −1], were collected ...
Search for leptonic decays of W′ bosons in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-08)
A search for a new heavy gauge boson W[superscript ′] decaying to an electron or muon, plus a low mass neutrino, is presented. This study uses data corresponding to an integrated luminosity of 5.0 fb[superscript −1], ...
Search for third-generation scalar leptoquarks in the tτ channel in proton-proton collisions at √s = 8 TeV
(Springer-Verlag, 2015-07)
A search for pair production of third-generation scalar leptoquarks decaying to top quark and τ lepton pairs is presented using proton-proton collision data at a center-of-mass energy of √s = 8 TeV collected with the CMS ...
Precise determination of the mass of the Higgs boson and tests of compatibility of its couplings with the standard model predictions using proton collisions at 7 and 8 TeV
(Springer-Verlag, 2015-05)
Properties of the Higgs boson with mass near 125 GeV are measured in proton-proton collisions with the CMS experiment at the LHC. Comprehensive sets of production and decay measurements are combined. The decay channels ...
