Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
(2018-01-01)
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 normalized differential tt¯ cross sections in the dilepton channel from pp collisions at s√=13 TeV
(2018-04-11)
Normalized differential cross sections for top quark pair production are measured in the dilepton (e⁺e⁻, μ⁺μ⁻, and μ∓e±) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are ...

(2012-04-06)
A search for the standard model Higgs boson decaying into two Z bosons with subsequent decay into a final state containing two quark jets and two leptons, H → ZZ(*) → q q¯ ℓ−ℓ+ is presented. Results are based on data ...
Measurement of quarkonium production cross sections in pp collisions at s=13TeV
(2018-05-10)
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
(2018-04-03)
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 ...
Study of hadronic event-shape variables in multijet final states in pp collisions at √s = 7TeV
(2014-10-14)
Event-shape variables, which are sensitive to perturbative and nonperturbative aspects of quantum chromodynamic (QCD) interactions, are studied in multijet events recorded in proton-proton collisions at √s = 7 TeV. Events ...
