We present the first study of charged-hadron production associated with jets originating from bquarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data sample used in this study was collected with the CMS detector at the CERNLHC and corresponds to an integrated luminosity of 27.4 pb−1. To characterize the jet substructure, the differential jet shapes, defined as the normalized transverse momentum distribution of charged hadrons as a function of angular distance from the jet axis, are measured for bjets. In addition to the jet shapes, the per-jet yields of charged particles associated with bjets are also quantified, again as a function of the angular distance with respect to the jet axis. Extracted jet shape and particle yield distributions for bjets are compared with results for inclusive jets, as well as with the predictions from the pythia and herwig++ event generators.
