Hadronic activity veto efficiencies in the signal-enriched BDT> 0.95 region for the muon and electron channels combined, as a function of the leading additional jet $p_T$. The data are compared with the background-only prediction as well as background+signal with PYTHIA parton showering and background+signal with HERWIG++ parton showering.
