摘要：
We report on hadron production at high transverse momentum from Au+Au collisions at roots(NN)= 130 GeV, measured with the STAR detector at the Relativistic Heavy Ion Collider (RHIC). Preliminary negative hadron spectra up to p(perpendicular to) = 6 GeV/c have been measured, and indicate a suppression at high p(perpendicular to) relative to a reference from p+(p) over bar collisions. Preliminary azimuthal anisotropies have been measured up to p(perpendicular to)=4.5 GeV/c, which are described well by a hydrodynamical calculation below 1.5 GeV/c, but show a significant deviation at higher p(perpendicular to). A preliminary ratio (p) over bar /p has been measured by the STAR-RICH detector in the range p(perpendicular to)=2-2.5 GeV/c.
