Centrality and transverse momentum dependence of D0 meson production at mid-rapidity in Au+Au collisions at sNN = 200GeV
All data are measured in mid-rapidity |y|<1 and at sqrt(s_NN) = 200 GeV.
D0 spectra in p+p collisions (the first two data points are measured for D0 and last four data points are for D* scaled with D0/D* fragmentation ratio from PYTHIA):
