Description
I will present next-to-leading order QCD predictions for the process of top quark pair production in association with a b-jet pair at the LHC with center of mass energy of 13 TeV. In the calculation we concentrated on the di-leptonic decay channel of the top quark pair and we considered full off-shell effects. This study is particularly relevant for the measurements of the Higgs properties, because it represents a background to the Higgs production in association with a top quark pair. In addition, our predictions might be used for precise measurements of the top quark fiducial cross sections and to improve top quark decay modeling at the LHC.
