Measurement of masses in the t[bar over t] system by kinematic endpoints in pp collisions at s√=7 TeV
(Springer-Verlag, 2013-07)
A simultaneous measurement of the top-quark, W-boson, and neutrino masses is reported for tt events selected in the dilepton final state from a data sample corresponding to an integrated luminosity of 5.0 fb[superscript ...
Search for single production of vector-like quarks decaying to a Z boson and a top or a bottom quark in proton-proton collisions at s=13$$ \sqrt{s}=13 $$ TeV
(Springer Nature, 2017-05)
A search for single production of vector-like quarks, T and B, decaying into a Z boson and a top or a bottom quark, respectively, is presented. The search is performed using data collected by the CMS experiment at the LHC ...
Study of the inclusive production of charged pions, kaons, and protons in pp collisions at √s = 0.9, 2.76, and 7 TeV
(Springer-Verlag, 2012-10)
Spectra of identified charged hadrons are measured in pp collisions at the LHC for √s = 0.9, 2.76, and 7 TeV. Charged pions, kaons, and protons in the transversemomentum range pT ≈ 0.1–1.7 GeV/c and for rapidities |y| < 1 ...
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
