Testing the chiral magnetic and chiral vortical effects in heavy ion collisions

We devise a test of the chiral magnetic and chiral vortical effects (CME and CVE) in relativistic heavy ion collisions that relies only on the general properties of triangle anomalies. We show that the ratio R_EB=J _E/J_B of charge J_E and baryon J_B currents for CME is REBCME→∞ for three light flavors of quarks (N_f=3), and REBCME=5 for N_f=2, whereas for CVE it is REBCVE=0 for N_f=3 and REBCME=1/2 for N_f=2. The physical world with light u,d quarks and a heavier s quark is in between the N _f=2 and N_f=3 cases; therefore, the ratios R_EB for CME and CVE should differ by over an order of magnitude providing a possibility to separate clearly the CME and CVE contributions. In both cases, there has to be a positive correlation between the charge and baryon number asymmetries that can be tested on the event-by-event basis.
