Title: Anomalous-hydrodynamic analysis of charge-dependent elliptic flow in heavy-ion collisions

Abstract

Anomalous hydrodynamics is a low-energy effective theory that captures effects of quantum anomalies. We develop a numerical code of anomalous hydrodynamics and apply it to dynamics of heavy-ion collisions, where anomalous transports are expected to occur. This is the first attempt to perform fully non-linear numerical simulations of anomalous hydrodynamics. We discuss implications of the simulations for possible experimental observations of anomalous transport effects. From analyses of the charge-dependent elliptic flow parameters (v$$±\atop{2}$$) as a function of the net charge asymmetry A ±, we find that the linear dependence of Δv$$±\atop{2}$$ ≡ v$$-\atop{2}$$ - v$$+\atop{2}$$ on the net charge asymmetry A ± cannot be regarded as a robust signal of anomalous transports, contrary to previous studies. We, however, find that the intercept Δv$$±\atop{2}$$ (A ± = 0) is sensitive to anomalous transport effects.
