B hadron properties at CMS

Precise measurements of B hadron properties are crucial to improve or constrain models based on non-perturbative quantum chromodynamics, which provide predictions of mass, lifetime, cross section, polarization, and branching ratios (among several other properties) of B hadrons. Measurements of CP violation in $B^0_s$ and properties of rare B decays also provide many opportunities to search for new physics. This article presents some B hadron property results obtained by CMS using Run~I (2011-2012) data, and prospects for the Run~II (2015-2017) data taking period.
