摘要：

The azimuthal angular dependence of the nuclear modification factor R-AA (p(T), phi, N-part) recently obtained by PHENIX is related at low p(T) to the trigger phi dependence of the ridge yield as measured by STAR in a framework in which the azimuthal anisotropy is driven by semihard scattering near the surface. Careful consideration of the initial geometry leads to the determination of a surface segment in which the production of semihard partons are responsible for the phi dependence of the inclusive distribution on the one hand and for the angular correlation in ridge phenomenology on the other. With v(2) also being well reproduced along with R-AA and ridge yield, all relevant phi dependencies in heavy-ion collisions can now be understood in a unified description that emphasizes the ridge production whether or not a trigger is used.
