The mechanism of production of heavy-flavoured mesons, containing b or c quarks, in association with vector bosons, W or Z, in the Standard Model is only partially understood. The deep understanding of these processes is furthermore required by Higgs and BSM analyses with similar final states. Using the LHC proton-proton collision data collected in 2011 at a centre of mass energy of 7 TeV by the CMS detector, a preliminary measurement of Z+b cross sections are presented in this poster. Z+b inclusive, Z+1b exclusive and Z+2b inclusive cross sections are determined for b hadron jets having pT > 25 GeV and |eta| < 2.1. The results are related to the following PAS : Measurement of the Z/γ*+bb-jets cross section in pp collisions at √s = 7 TeV with the CMS detector, CMS PAS SMP-12-003.
