Abstract
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 of charge and baryon currents for CME is for three light flavors of quarks (), and for , whereas for CVE it is for and for . The physical world with light quarks and a heavier quark is in between the and cases; therefore, the ratios 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.
