Studies of beauty suppression via nonprompt D-0 mesons in Pb-Pb collisions at root s(NN)=5.02 TeV

The transverse momentum spectra of D0 mesons from b hadron decays are measured at midrapidity (jyj < 1) in pp and Pb-Pb collisions at a nucleon-nucleon center of mass energy of 5.02 TeV with the CMS detector at the LHC. The D0 mesons from b hadron decays are distinguished from prompt D0 mesons...
