Abstract:

    We report the first measurements of D0-meson production at mid-rapidity (|y| < 1) in isobar collisions (96Ru+96Ru and 96Zr+96Zr) at √sNN = 200 GeV with the STAR experiment. D0 pT differential invariant yield with transverse momentum pT < 8 GeV/c are reported in 0-10%, 10-40% and 40-80% centrality. The D0 production cross section follows the number of binary collisions scaling within systematic uncertainties between isobar and Au+Au collisions at 200 GeV. The strong suppression D0 nuclear modification factor RAA is also observed for pT > 3 GeV/c in the central isobar collisions, demonstrating that charm quarks suffer significant energy loss in the bulk QCD medium. And model calculations reproduce the feature of RAA measured at 200 GeV.
