Measurement of top quark-antiquark pair production in association with a W or Z boson in pp collisions at root s=8 TeV
A measurement of the cross section for the production of top quark-antiquark pairs (t (t) over bar) in association with a vector boson V (W or Z) in proton-proton collisions at root s = 8 TeV is presented. The results are based on a dataset corresponding
