Hydrodynamics and the Detection of the QCD Axial Anomaly in Heavy Ion Collisions

Abstract

We consider the experimental implications of the axial current triangle diagram anomaly in a hydrodynamic description of high density QCD. We propose a signal of an enhanced production of spin-excited hadrons in the direction of the rotation axis in off-central heavy ion collisions.
