Production of ? mesons in p + p, d + Au, Cu + Cu, and Au + Au collisions at (radical)sNN=200 GeV
Original language description
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured ? meson production via leptonic and hadronic decay channels in p + p, d + Au, Cu + Cu, and Au + Au collisions at (radical)sNN = 200 GeV. The invariant transverse momentum spectra measured in different decay modes give consistent results. Measurements in the hadronic decay channel in Cu + Cu and Au + Au collisions show that ? production has a suppression pattern at high transverse momentum, similar to that of ?0 and ? in central collisions, but no suppression is observed in peripheral collisions. The nuclear modification factors, RAA, are consistent in Cu + Cu and Au + Au collisions at similar numbers of participant nucleons.
