Following significant theoretical advancements, jet vetoes, or 0-jet binning techniques, are increasingly used in measurements and searches at the LHC as powerful means to reduce Standard Model backgrounds. After reviewing these advancements for a non-expert audience, we present an unusual (dynamic) implementation of a jet veto, one that discriminates on an event-by-event basis, and precisely targets so-called irreducible backgrounds. While significantly improving signal-over-background rates for multi-lepton searches, the veto exhibits somewhat desirable theoretical properties and suggests a reduced need for high-precision jet veto resummation. As benchmarks, the impact on searches for heavy neutrinos [1805.09335,1812.08750] and sleptons [1901.09937] at the 14 TeV LHC are presented.
