Nuclear modification factor of D0 mesons in PbPb collisions at sNN=5.02TeV

The transverse momentum (pT) spectrum of prompt D0 mesons and their antiparticles has been measured via the hadronic decay channels D0 → K−π+ and D0 → K+π− in pp and PbPb collisions at a centre-of-mass energy of 5.02 TeV per nucleon pair with the CMS detector at the LHC. The measurement is perfor...
