Associated production of a top-quark pair with vector bosons at NLO in QCD: impact on $t\bar{t}H$ searches at the LHC

Fabio Maltoni, Davide Pagani, Ioannis Tsinikos

We study the production of a top-quark pair in association with one and two vector bosons, $t\bar{t}V$ and $t\bar{t}VV$ with $V=\gamma ,Z,W^{\pm }$, at the LHC. We provide predictions a…
