Conformal anomaly and photon anisotropy in heavy ion collisions

I introduce a novel mechanism for anisotropic photon production in heavy ion collisions, stemming from the interplay between anomalies of QCDxQED and the existence of strong (electro)magnetic fields. For the case of conformal anomaly, using the hydrodynamical description of the bulk modes of QCD plasma, I show that this mechanism leads to the pho- ton production yield that is comparable to the yield from conventional sources. Furthermore, this mechanism provides a a significant positive contribution to the azimuthal anisotropy of photons (v2) and shows agree- ment with the PHENIX data.
