Measurement of the t(t)over-bar production cross section in the dilepton channel in pp collisions at root s=8 TeV
The top-antitop quark (t (t) over bar) production cross section is measured in proton-proton collisions at root s = 8 TeV with the CMS experiment at the LHC, using a data sample corresponding to an integrated luminosity ...
Search for pair production of excited top quarks in the lepton plus jets final state
A search is performed for pair-produced spin-3/2 excited top quarks , each decaying to a top quark and a gluon. The search uses data collected with the CMS detector from pp collisions at a center-of-mass energy of = 8 TeV, ...
Measurement of the W-boson helicity in top-quark decays from t(t)over-bar production in lepton plus jets events in pp collisions at root s=7 TeV
The W-boson helicity fractions in top-quark decays are measured with t (t) over bar events in the lepton+jets final state, using proton-proton collisions at a centre-of-mass energy of 7 TeV, collected in 2011 with the CMS ...
