Rapidity dependence of elliptic and triangular flow in proton–nucleus collisions from collective dynamics
Abstract
The rapidity dependence of elliptic, v2, and triangular, v3, flow coefficients in proton–nucleus (p+A) collisions is predicted in hydrodynamics and in a multi-phase transport model (AMPT). We find that vn (n=2,3) on a nucleus side is significantly larger than on a proton side and the ratio between the two, vnPb/vnp, weakly depends on the transverse momentum of produced particles.
