| Özet |
| The first measurement of vector-boson production associated with a top quark-antiquark pair in proton-proton collisions at is presented. The results are based on a data set corresponding to an integrated luminosity of , recorded by the CMS detector at the LHC in 2011. The measurement is performed in two independent channels through a trilepton analysis of events and a same-sign dilepton analysis of ( or ) events. In the trilepton channel a direct measurement of the cross section is obtained. In the dilepton channel a measurement of the cross section yields . These measurements have a significance, respectively, of 3.3 and 3.0 standard deviations from the background hypotheses and are compatible, within uncertainties, with the corresponding next-to-leading order predictions of and . |
