The production cross section of top-quark pairs associated with a photon (ttbar+gamma) is determined in the muon+jets decay channel using 19.7 fb-1 of data taken at sqrt(s) = 8 TeV with the CMS detector. The relative fraction of ttbar+gamma events normalized to inclusive ttbar production is measured. Using an inclusive CMS cross section measurement, the ttbar+gamma cross section is determined...

A differential cross section measurement of the top quark pair production with respect to the global variables missing transverse energy (ETmiss), jet transverse momentum sum (HT), total observed transverse momentum sum (ST), W-boson transverse mass (MTW) and W-boson transverse momentum (pTW) is presented here using approximately 5.0fb-1 of data from CMS at √s=7TeV and 19.7fb-1 of data at...

The first measurement of the cross section ratio sigma(t t-bar b b-bar) / sigma(t t-bar jj) is presented using a data sample corresponding to an integrated luminosity of 19.6 inverse femtobarns collected in pp collisions at sqrt(s) = 8 TeV with the CMS detector at the LHC. Events with two leptons (e or mu) and four reconstructed jets, including two identified as b quark jets, in the final...
