We study the local violation of P and CP invariance in heavy ion collisions as observed at RHIC and LHC using a simple deformed QCD model. This model is a weakly coupled gauge theory, which however has all the relevant crucial elements allowing us to study difficult and nontrivial questions which are known to be present in real strongly coupled QCD. Essentially, we want to understand the physics of long range order in form of coherent low-dimensional vacuum configurations observed in Monte Carlo lattice simulations. Apparently precisely such kind of configurations are responsible for sufficiently strong intensity of asymmetries observed in heavy ion collisions. (c) 2012 Elsevier B.V. All rights reserved.
