High $P\perp$ spectra from Au+Au collisions at $\sqrt{s_{NN}}$ = 130 GeV

We report on hadron production at high transverse momentum from Au+Au collisions at _/sNN = 130GeV, measured with the STAR detector at the Relativistic Heavy Ion Collider (RHIC). Preliminary negative hadron spectra up to p| relative to a reference from p + p collisions. Preliminary azimuthal anisotr...

Sumario:We report on hadron production at high transverse momentum from Au+Au collisions at _/sNN = 130GeV, measured with the STAR detector at the Relativistic Heavy Ion Collider (RHIC). Preliminary negative hadron spectra up to p| relative to a reference from p + p collisions. Preliminary azimuthal anisotropies have been measured up to p| = 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|. A preliminary ratio p/p has been measured by the STAR-RICH detector in the range p| = 2-2.5 GeV/c.
