摘要：

Results on high transverse momentum charged particle emission with respect to the reaction plane are presented for Au+Au collisions at roots(NN=)200 GeV. Two- and four-particle correlations results are presented as well as a comparison of azimuthal correlations in Au+Au collisions to those in p+p at the same energy. The elliptic anisotropy v(2) is found to reach its maximum at p(t)similar to3 GeV/c, then decrease slowly and remain significant up to p(t)approximate to7-10 GeV/c. Stronger suppression is found in the back-to-back high-p(t) particle correlations for particles emitted out of plane compared to those emitted in plane. The centrality dependence of v(2) at intermediate p(t) is compared to simple models based on jet quenching.
