Abstract: The results of midrapidity (0<y<0.8) neutral pion spectra over an extended transverse momentum range (1<pT<12 GeV/c) in sNN=200 Ge, Au+Au collisions, measured by the STAR experiment, are presented. The neutral pions are reconstructed from photons measured either by the STAR Barrel Electro-Magnetic Calorimeter or by the Time Projection Chamber via tracking of conversion electron-positron pairs. Our measurements are compared to previously published π± and π0 results. The nuclear modification factors RCP and RAA of π0 are also presented as a function of pT. In the most central Au+Au collisions, the binary collision scaled π0 yield at high pT is suppressed by a factor of about 5 compared to the expectation from the yield of p+p collisions. Such a large suppression is in agreement with previous observations for light quark mesons and is consistent with the scenario that partons suffer considerable energy loss in the dense medium formed in central nucleus-nucleus collisions at the Relativistic Heavy Ion Collider. © 2009 The American Physical Society.
