Description | Joint Theory Seminar Speaker: Felix Yu (UC Irvine) Title: A New Method for Resolving Combinatorial Ambiguities at Hadron Colliders Host: Hsin-Chia Cheng Room: 432 Abstract: We present a new method for resolving combinatorial ambiguities that arise in multi-particle decay chains at hadron colliders where the assignment of visible particles to the different decay chains has ambiguities. Our method, based on selection cuts favoring high transverse momentum and low invariant mass pairings, is shown to be significantly superior to the more traditional hemisphere method for a large class of decay chains, producing an increase in signal retention of up to a factor of 2. This new method can thus greatly reduce the combinatorial ambiguities of decay chain assignments. |
