Abstract
The first study of the shapes of jets arising from bottom (b) quarks in heavy ion collisions is presented.
Jet shapes are studied using charged hadron constituents as a function of their radial distance from the
jet axis. Lead-lead (PbPb) collision data at a nucleon-nucleon center-of-mass energy of √sNN = 5.02 TeV
were recorded by the CMS detector at the LHC, with an integrated luminosity of 1.69 nb−1. Compared
to proton-proton collisions, a redistribution of the energy in b jets to larger distances from the jet axis is
observed in PbPb collisions. This medium-induced redistribution is found to be substantially larger for b
jets than for inclusive jets.
