Thanks to the excellent tracking and muon identification performance,
combined with a flexible trigger system, the CMS experiment at the Large Hadron
Collider is conducting a rich and competitive program of measurements in the
field of heavy flavor physics. We review the status of b-quark production cross
section measurements in inclusive and exclusive final states, the measurement
of B hadron angular correlations, the search for rare Bs0​ and B0 decays
to dimuons, and the observation of the X(3872) resonance.Comment: Presented at the 2011 Hadron Collider Physics symposium (HCP-2011),
