 We could think of implementing a b-jet veto as an option in the rivet routine, but this would only be approximate,​ since the analysis cut is done at the detector level with a combination of a b-tagging discriminant (above 30 GeV $p_T$) and a soft muon requirement (with some lower efficiency between 15 and 30 GeV) and we don't have the smearing or efficiency functions. The net result would presumably be to reduce the sensitivity toward the level of the other We could think of implementing a b-jet veto as an option in the rivet routine, but this would only be approximate,​ since the analysis cut is done at the detector level with a combination of a b-tagging discriminant (above 30 GeV $p_T$) and a soft muon requirement (with some lower efficiency between 15 and 30 GeV) and we don't have the smearing or efficiency functions.
