Evidence of b-Jet Quenching in PbPb Collisions at √sNN = 2.76 TeV

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 (pT) range of 80–250 GeV/c, and within pseudorapidity |η|<2. The nuclear modification...
