Five-flavour scheme predictions for tt¯bb¯ at next-to-leading order accuracy

Abstract

We compute top quark pair production in association with a bottom quark pair at the LHC within the five-flavour scheme, matched to a parton shower, employing the FxFx merging scheme for tt¯+jets production with up to 2 jets at NLO accuracy. To enhance the selection efficiency for the events with b-jets within the inclusive five-flavour sample, we augment the generation probability of bottom quark flavours in the short-distance event generation. Our analysis reveals some differences from NLO predictions within the four-flavour scheme.
