Abstract

This document describes my talk (based on work by JoAnne Hewett, Sandip Pakvasa, Alexey Petrov, Gagik Yeghiyan and myself) given at the 2011 Meeting of the Division of Particles and Fields of the American Physical Society (8/9/11-8/13/11) hosted by the Physics Department at Brown University. We perform a study of the Standard Model (SM) fit to the mixing quantity Delta M_B_s in order to bound contributions of New Physics (NP) to B_s mixing. We then use this to explore the branching fraction of B_s->mu+mu- in several models of New Physics.
