摘要：
The pi(0) meson has been a crucial probe for observing jet quenching in ultrarelativistic heavy-ion collisions at RHIC. Measurements of the eta meson in the same collisions have also shed light on a possible dependence of the observed suppression on the particle species. The preliminary pi(0) nuclear modification factor R-AA from the 2004 RHIC run allowed a first systematic comparison between a precise measurement with high statistics and theoretical calculations, constraining model parameters such as the initial gluon density dN(g)/dy, and the transport coefficient (q) over cap. The final pi(0) spectra and R-AA are shown as well as the first eta results obtained with both PHENIX electromagnetic calorimeters.
