Description
High-$p_T$, multi-lepton events remain one of the most sensitive probes of new physics at the LHC. Despite this, multi-weak boson and top quark-associated production channels remain leading Standard Model backgrounds for these signatures. We present a new class of jet vetoes, one that is defined on an event-by-event basis, that precisely targets these so-called irreducible backgrounds and can significantly improve signal-over-background significance. The veto exhibits somewhat desirable theoretical properties and suggests a lesser need for high order jet veto resummation. Applications to searches for lepton number and lepton flavor violation at $\sqrt{s}=14$ and 100 TeV are shown.
