The Compact Muon Solenoid (CMS) is a multi-purpose detector which will
be operated at the Large Hadron Collider (LHC) at CERN. Its excellent
tracking system, combined with low transverse momentum muon trigger
capabilities, allow for precise studies of heavy flavor decays. The
capabilities of the CMS experiment in this field have been studied in
several benchmark processes. These studies are based on a full detector
simulation and show the capability of CMS to identify, select and
reconstruct heavy flavor decays, which present a significant challenge
due to the relatively low momentum and high background. After a
description of the detector, the trigger system and the trigger strategy
for B physics, several heavy flavor analyses in CMS will be presented
including the exclusive Bs decays to J/psi phi, and to mu+mu-, the decay
tau to 3mu, and Bc and direct charmonium production.
