Measurement of associated production of vector bosons and top quark-antiquark pairs in pp collisions at √s=7 TeV
(2013)Physical Review LettersThe first measurement of vector-boson production associated with a top quark-antiquark pair in proton-proton collisions at √s=7 TeV is presented. The results are based on a data set corresponding to an integrated luminosity of 5.0 fb−1, recorded by the CMS detector at the LHC in 2011. The measurement is performed in two independent channels through a trilepton analysis of t¯tZ events and a same-sign dilepton analysis of t¯tV (V=W or Z) ...Journal Article
