摘要

In this Erratum we report changes on the D 0 pT spectra and nuclear modification factor (RAA) in Au þ Au collisions at ffiffiffiffiffiffiffiffi sNN p ¼ 200 GeV by fixing the errors in the efficiency and selection criteria that affected the Au þ Au results. The p þ p reference spectrum has changed as well and is updated with new fragmentation parameters. In this Letter, we reported on measurements of the nuclear modification factor of D 0 mesons in Au þ Au collisions at ffiffiffiffiffiffiffiffi sNN p ¼ 200 GeV. We have identified two errors in the estimation of the particle identification efficiency. Considering the high combinatorial background in D 0 meson reconstruction in Au þ Au collisions, a hybrid particle identification method was used in this analysis to improve significance of the signal. For p< 1.6 GeV= c, pion and kaon candidates were selected by requiring a selection on the ionization energy loss of the particle passing through …
