Аннотация
Results on high transverse momentum charged particle emission with respect to the reaction plane are presented for $\mathrm{A}\mathrm{u}+\mathrm{A}\mathrm{u}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}$. Two- and four-particle correlations results are presented as well as a comparison of azimuthal correlations in $\mathrm{A}\mathrm{u}+\mathrm{A}\mathrm{u}$ collisions to those in $p+p$ at the same energy. The elliptic anisotropy ${v}_{2}$ is found to reach its maximum at ${p}_{t}\ensuremath{\sim}3\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/c$, then decrease slowly and remain significant up to ${p}_{t}\ensuremath{\approx}7--10\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/c$. 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.
