“…3, the uncorrelated transverse asymmetry between initial spatial and final momentum are shown similarly in the two system. It implies that the dynamic and/or dynamic fluctuations play an important role in system evolution stage [21] i.g., the final transverse asymmetry gets a large contribution from the evolution of dynamic.…”

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.

“…There are also direct simulations of the fluctuating hydrodynamics on the numerical grid [37,38,39,40,41,42]. One of the important phenomenological consequences of the thermal noise is longitudinal decorrelation of the particle flows [42]. The longitudinal correlation of particle flows with η a and −η a can be measured by r…”

In this paper, we use a multi-phase transport model to simulate the parton evolution time-dependent transverse asymmetry in peripheral Pb–Pb ([Formula: see text]–15[Formula: see text]fm) and p–Pb ([Formula: see text]–1[Formula: see text]fm) collisions at [Formula: see text][Formula: see text]TeV, respectively. The simulated results showed that the initial spatial asymmetry depends on the collision system, while both the initial momentum asymmetry and final momentum asymmetry are independent on the collision system. It is also shown that the final momentum asymmetry is similar to the initial momentum asymmetry. Furthermore, the averaged transverse shape asymmetry, which includes the initial spatial asymmetry, the initial momentum asymmetry, and the final momentum asymmetry, is significantly dependent on the transverse momentum and particle species identity (PID). The PID scales ordering transverse asymmetry indicated that it provides a possible observation for studying the fluctuating droplet properties of quark–gluon plasma, which may produce in heavy-ion collisions.
