【 摘 要 】

We report new results on v(sub 2)(p(sub T)) for Au+Au collisions at (radical)(S(sub NN))= 200 GeV for charged hadrons, pions, kaons, (anti)protons, K(sub s)(sup O), and Lambda. The analysis is extended to p(sub T)= 12 GeV/c for charged hadrons and p(sub T)= 4 GeV/c for identified particles. A comparison of the azimuthal anisotropy of charged hadrons measured at sqrt(radical)(s(sub NN))= 130 and 200 GeV is presented. The p(sub T)-dependence of baryon versus meson elliptic flow is discussed.
