Abstract
In this contribution we report a recently developed Anomalous-Viscous Fluid Dynamics (AVFD) framework, which simulates the evolution of fermion currents in QGP on top of the bulk expansion from data-validated VISHNU hydrodynamics. With reasonable estimates of initial conditions and magnetic field lifetime, the predicted CME signal is quantitatively consistent with change separation measurements in 200GeV Au-Au collisions at RHIC. We further develop the event-by-event AVFD simulations that allow direct evaluation of two-particle correlations arising from CME signal as well as the non-CME backgrounds. Finally we report predictions from AVFD simulations for the upcoming isobaric (Ru-Ru v.s. Zr-Zr ) collisions that could provide the critical test of the CME in heavy ion collisions.

The Chiral Magnetic Effect (CME) [1, 2] refers to the generation of an electric current JQ along the magnetic field B applied to a system of chiral fermions with chirality imbalance, i.e
Given the magnificent physics embodied in the Chiral Magnetic Effect, it is of the utmost interest to search for its manifestation in the quark-gluon plasma (QGP) created in relativistic heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC)
Dedicated searches for potential CME signals have been ongoing at RHIC and the LHC [3, 4, 5, 6], with encouraging evidences reported through measuring the charge separation signal induced by the CME current (1)
Summary
The Chiral Magnetic Effect (CME) [1, 2] refers to the generation of an electric current JQ along the magnetic field B applied to a system of chiral fermions with chirality imbalance, i.e. The most pressing challenge for the search of CME in heavy ion collisions is to clearly separate background contributions from the desired signal. As the key ingredients for driving the CME current, the magnetic field and the initial axial charge density are the most important inputs for the AVFD simulation.
