Description
Measurements and searches are presented of association top production processes (ttV and tV) in pp collisions at sqrt(s) = 13 TeV recorded by CMS and ATLAS. ttW is measured in the two same-sign lepton channel, obtaining an expected (observed) significance of 4.5 (5.3) standard deviations in the CMS analysis and (3.4) 3.9 in the ATLAS analysis. ttZ associated production is measured in the three and four lepton channel with a significance of above 5 standard deviations. tZq is measured in the three lepton channel with an observed (expected) significance of 3.1 (3.7) sigmas in the CMS analysis and 4.2 (5.4) in the ATLAS one. tW is measured in the opposite-sign electron-muon channel with a precision of 10% by CMS and in the opposite-sign dilepton channel with a precision of 30% by ATLAS.
