Highp_T physics at STAR

摘要

We discuss the capabilities of STAR in exploring the physics at highp _T in ultrarelativistic heavy-ion colisions from RHIC at √s _NN = 130 GeV Preliminary results show that the spectra of negatively charged particles get suppressed at largerp _T in comparison top-p data. A strong azimuthal anisotropy observed at large transverse momentum region. A preliminary ratio -p/p has been measured by STAR-RICH detector. Some ongoing studies and future plans are discussed.
