$\textrm{t}\bar{\textrm{t}} \textrm{b}\bar{\textrm{b}}$ modeling for $\textrm{t}\bar{\textrm{t}} \textrm{H}$ analyses in ATLAS and CMS

An overview of the Monte Carlo modelling of the top quark pair production in association with bottom quarks ($\textrm{t}\bar{\textrm{t}} \textrm{b}\bar{\textrm{b}}$), is presented. This process is a cornerstone for the $\textrm{t}\bar{\textrm{t}} \textrm{H}(\textrm{b}\bar{\textrm{b}})$ analyses performed by both ATLAS and CMS experiments at the Large Hadron Collider (LHC).
