Description
Latest results on inclusive top quark pair and single top quark production cross sections are presented using proton-proton collision data collected by CMS at different centre-of-mass energies, including 5 TeV. The single top quark analyses investigate separately the production of top quarks via t-channel exchange, in association with a W boson (tW) or via the s-channel. Final states with at least one charged lepton and one b-jet are explored to measure inclusive production cross sections. The sensitivity of some these measurements to PDFs and extraction of standard model parameters is also described. Moreover, first ttbar cross sections results in proton-lead collisions are discussed.
