New NLOPS predictions for $\boldsymbol{t\bar{t}+b}$-jet production at the LHC

12 Jul 2018 Ježo Tomáš Lindert Jonas M. Moretti Niccolo Pozzorini Stefano

Measurements of $t\bar{t} H$ production in the $H\to b\bar{b}$ channel depend in a critical way on the theoretical uncertainty associated with the irreducible $t\bar{t}+b$-jet background. In this paper, analysing the various topologies that account for $b$-jet production in association with a $t\bar{t}$ pair, we demonstrate that the process at hand is largely driven by final-state $g\to b\bar{b}$ splittings...
