ttbar+Boson (except Higgs)

The latest results for processes with a top-pair and an associated vector boson are presented. Both the ATLAS and the CMS collaborations have improved their previous results such that the observations of ttZ, ttW and ttγ are at, or beyond, discovery significances. The cross-sections for these proces...

Sumario:The latest results for processes with a top-pair and an associated vector boson are presented. Both the ATLAS and the CMS collaborations have improved their previous results such that the observations of ttZ, ttW and ttγ are at, or beyond, discovery significances. The cross-sections for these processes are important for constraints on new physics models, in particular for models which go beyond the Standard Model regarding the mechanism for generation of mass.
