Towards NNLO QCD predictions for off-shell top-quark pair production and decays

Luca Buonocore, Massimiliano Grazzini, Stefan Kallweit +2

We consider QCD radiative corrections to $W^{+}{W}^{-}b\bar{b}$ production with leptonic decays and massive bottom quarks at the LHC. We perform an exact next-to-leading order (NLO) ca…
