Recent CMS heavy flavor physics results

In this paper, recent results in the B-physics field achieved using proton-proton collision data at root s = 8 and 13 TeV collected by CMS are presented. They include the angular analysis of the decay B+ -> K*mu(+)mu(-) with Run 1 data, new measurements of D and B meson production cross-sections and CP violation studies using B-s(0) decays with Run 2 data. The results are compared with the Standard Model predictions. A measurement of the CP-violating phase phi(s) achieved by combining results from both Run 1 and Run 2 data is also presented.
