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...

| description | 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 by
their decay topologies. In Pb-Pb collisions, the B → D0 yield is found to be suppressed in the measured pT
range from 2 to 100 GeV=c as compared to pp collisions. The suppression is weaker than that of prompt
D0 mesons and charged hadrons for pT around 10 GeV=c. While theoretical calculations incorporating
partonic energy loss in the quark-gluon plasma can successfully describe the measured B → D0
suppression at higher pT, the data show an indication of larger suppression than the model predictions
in the range of 2 < pT < 5 GeV=c. |
