Measurements of the associated production of a
Z
boson with at least one jet originating from a b quark in proton-proton collisions at

are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8

Z
bosons are reconstructed through their decays to electrons and muons. Cross sections are measured as a function of observables characterizing the kinematics of the
b
jet and the
Z
boson. Ratios of differential cross sections for the associated production with at least one
b
jet to the associated production with any jet are also presented. The production of a
Z
boson with at least two
b
jets is investigated, and differential cross sections are measured for the dijet system. Results are compared to theoretical predictions, testing two different flavour schemes for the choice of initial-state partons.
