Constraints on the double-parton scattering cross section from same-sign W boson pair production in proton-proton collisions at √s=8 TeV
A first search for same-sign WW production via double-parton scattering is performed based on proton-proton collision data at a center-of-mass energy of 8 TeV using dimuon and electron-muon final states. The search is based ...
Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance pTmiss in transverse momentum. The data were collected ...
Measurement of quarkonium production cross sections in pp collisions at s=13TeV
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=13TeV, with data collected by the CMS detector at the LHC, ...
Measurement of the Splitting Function in pp and Pb-Pb Collisions at sNN =5.02 TeV
Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the ...
Search for supersymmetry in events with at least three electrons or muons, jets, and missing transverse momentum in proton-proton collisions at √s=13 TeV
A search for new physics is carried out in events with at least three electrons or muons in any combination, jets, and missing transverse momentum. Results are based on the sample of proton-proton collision data produced ...
