Observation of top quark pairs produced in association with a vector boson in pp collisions at root s=8 TeV
(Journal of High Energy Physics, 2016)
Measurements of the cross sections for top quark pairs produced in association with a W or Z boson are presented, using 8 TeV pp collision data corresponding to an integrated luminosity of 19.5 fb(-1), collected by the CMS ...
Search for the associated production of the Higgs boson with a top-quark pair
(Journal of High Energy Physics, 2014)
A search for the standard model Higgs boson produced in association with a top-quark pair (t (t) over barH) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb(-1) and 19.7 fb(-1) ...
