Abstract

The flavor-changing neutral current decay B_s->mu mu is highly suppressed in the standard model, but its branching fraction of 3.4*10^-9 could be significantly enhanced through contributions from new physics. At the LHC, this rare decay could be observed for the first time. In this contribution, the prospects for measuring B_s->mu mu with the CMS detector are presented. In particular, some aspects of the experimental setup, the first and high level trigger selections, and the offline analysis are discussed.
