Measurements of t(t)over-bar charge asymmetry using dilepton final states in pp collisions at root s=8 TeV
The charge asymmetry in ttevents is measured using dilepton final states produced in ppcollisions at the LHC at root s = 8 TeV. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of ...
Measurement of the W boson helicity fractions in the decays of top quark pairs to lepton plus jets final states produced in pp collisions at root s=8 TeV
The W boson helicity fractions from top quark decays in t (t) over bar events are measured using data from proton-proton collisions at a centre-of-mass energy of 8 TeV. The data were collected in 2012 with the CMS detector ...
Search for standard model production of four top quarks in proton-proton collisions at root s=13TeV
A search for events containing four top quarks (t (t) over bart (t) over bar) is reported from proton-proton collisions recorded by the CMS experiment at root s = 13 TeV and corresponding to an integrated luminosity of 2.6 ...
