Parton evolution time dependent transverse shape asymmetry in peripheral Pb-Pb and p-Pb collisions at 5.02 TeV

Abstract

We use A Multi-Phase Transport (AMPT) model to simulate the parton evolution time dependent transverse asymmetry in peripheral Pb-Pb (b=14-15 fm) and p-Pb (b=0-1 fm) collisions at √ sNN = 5.02 TeV, respectively.The simulated results have shown that the initial asymmetry both of spatial and momentum are dependence on collision system, and the final asymmetry are independence on collision system, as a result of collision system expansion in the non-equilibrium dynamic. By the evolution time step, we extract the response coefficients from quantities between final asymmetry and time dependent transverse asymmetry. Such asymmetry response coefficients are strongly dependence on collision system. The evolution time dependent transverse asymmetry indicated that it provides a possible observation for studying the fluctuating droplet properties of Quark-Gluon Plasma (QGP), which is may produce in heavy ion collisions.
