Determination of the top-quark pole mass and strong coupling constant from the tt production cross section in pp collisions at root s=7 TeV
(Elsevier, 2014-01-20)The inclusive cross section for top-quark pair production measured by the CMS experiment in proton–proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order ... -
Limits on the Higgs boson lifetime and width from its decay to four charged leptons
(American Physical Society, 2015-10-01)Constraints on the lifetime and width of the Higgs boson are obtained from H→ZZ→4ℓ events using data recorded by the CMS experiment during the LHC run 1 with an integrated luminosity of 5.1 and 19.7 fb−1 at a center-of-mass ... -
