| contents | In this paper the non-perturbative suppression of the Chiral Magnetic Effect (CME) is investigated in the deconfined region of the QCD phase diagram (as a model for Quark-Gluon Plasma (QGP) emerging in Heavy Ion Collisions (HIC)), using the Kubo formula to calculate a linear response to the chiral imbalance, and the Field Correlator Method to address the strong interaction in QCD. The estimate suggests that CME is severely suppressed in most of the QCD phase diagram, except within a narrow strip at baryon densities above nuclear and temperatures just above the deconfinement transition. The result suggests refining the conditions under which the CME might be observable -- prioritizing the conditions at lower energy RHIC-BES, SPS and upcoming FAIR, NICA, J-PARC-HI, which supposedly produce high baryon density QGP, over the higher energy RHIC and LHC, which produce high temperature QGP. |
