Abstract: A measurement of the double differential cross section for inclusive b jet production in proton-proton collisions as well as fraction of b jets in the inclusive jet production is presented as a function of the transverse momentum p T and the absolute rapidity |y|. The data samples were collected in the CMS experiment at LHC during 2016 and correspond to an integrated luminosity of 35.2 fb −1 at a centre-of-mass energy of 13 TeV. The jets are selected with p T > 74 GeV and |y| < 2.4; the b jets must contain a B hadron. The measurement has significant statistics up to p T ∼ O(TeV). Advanced methods of unfolding are performed to extract the signal. It is found that fixed-order calculations with underlying event describe the measurement well.
