Abstract: We present studies of the b_bbar_4l (bb4l) package from the POWHEG BOX RES Monte Carlo generator, used to model top quark productions for the CMS experiment at the LHC. The bb4l package includes next-to-leading order matrix element calculations interfaced to parton shower for top quark pair production, the associated production of a single top quark with a W boson, their interferences, and the non-resonant production of two charged leptons, two neutrinos, and two b quarks. Events generated with the bb4l package are compared to predictions from the POWHEG BOX V2 generators across several observables sensitive to off-shell and interference effects.
