"Measurement of b jet shapes in proton-proton collisions at s√= 5.02 TeV." <i>Journal of High Energy Physics,</i> 2021, (2021) Springer Nature: https://doi.org/10.1007/JHEP05(2021)054.https://hdl.handle.net/1911/110672We present the first study of charged-hadron production associated with jets originating from b quarks 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 CERN LHC 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 b jets. In addition to the jet shapes, the per-jet yields of charged particles associated with b jets 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 b jets are compared with results for inclusive jets, as well as with the predictions from the pythia and herwig++ event generators.engThis article is distributed under the terms of the Creative Commons Attribution License (CC-BY 4.0), which permits any use, distribution and reproduction in any medium, provided the original author(s) and source are credited.Journal articleMeasurementOfBJetShapesInProtohttps://doi.org/10.1007/JHEP05(2021)054
