Evidence for the associated production of a vector boson (W, Z) and top quark pair in the dilepton and trilepton channels in pp collision data at $\sqrt{s}=8$ TeV collected by the ATLAS detector at the LHC
Measurements of the production cross sections of top quark pairs in association with a $W$ or $Z$ boson using a data set corresponding to 20.3 ${\rm fb}^{-1}$ of integrated luminosity collected by the ATLAS detector in 2012 are presented. Final states with two or three leptons are considered. Assumi...
