CANCELLED: Going over the top

This event is part of the HET Seminar Series.

Abstract: Final states with many tops appear in various extensions of the Standard Model (SM). Alas, top reconstruction faces combinatorial issues as they show up as large multiplicity events. In this talk, we present a new procedure to reconstruct multi-top final states. We establish the use of this procedure to purify the sample of SM tops from other SM contributions (W+jets, Z+jets). We also propose an alternative measurement of the top mass based on this strategy. Finally, we demonstrate the usefulness of the procedure for the more challenging situation with a four-top final state.
