### Event details

Multi-jet rates are one of the most coveted LHC observables. In this seminar I present recent work developing a statistical understanding for ratios of exclusive jet multiplicities. As analogies for the full QCD evolution, I relate a toy model for an iterated Poisson distribution, the final state cascade using the generating functional language, and the complete parton shower. Finally, I will mention possible applications for these methods including improved jet veto predictions in Higgs searches.

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
