Partonic Flow and-Meson Production inAu+AuCollisions atsNN=200GeV Academic Article uri icon

abstract

  • We present first measurements of the -meson elliptic flow (v2(pT)) and high-statistics pT distributions for different centralities from sNN=200GeV Au+Au collisions at RHIC. In minimum bias collisions the v2 of the meson is consistent with the trend observed for mesons. The ratio of the yields of the to those of the as a function of transverse momentum is consistent with a model based on the recombination of thermal s quarks up to pT 4GeV/c, but disagrees at higher momenta. The nuclear modification factor (RCP) of follows the trend observed in the KS0 mesons rather than in baryons, supporting baryon-meson scaling. These data are consistent with mesons in central Au+Au collisions being created via coalescence of thermalized s quarks and the formation of a hot and dense matter with partonic collectivity at RHIC. 2007 The American Physical Society.
