Abstract
The production of jets associated to bottom quarks is measured for the first time in PbPb collisions at a center-of-mass energy of 2.76 TeV per nucleon pair. Jet spectra are reported in the transverse momentum () range of , and within pseudorapidity . The nuclear modification factor () calculated from these spectra shows a strong suppression in the -jet yield in PbPb collisions relative to the yield observed in collisions at the same energy. The suppression persists to the largest values of studied, and is centrality dependent. The is about 0.4 in the most central events, similar to previous observations for inclusive jets. This implies that jet quenching does not have a strong dependence on parton mass and flavor in the jet range studied.

The Stopping Power of Hot Nuclear Matter
Published 22 September 2014
LHC experiments show that the quark-gluon plasma stops jets made of light and heavy quarks equally well, offering insights into a state of matter thought to have existed in the early Universe.
