Photon radiation by fermions rotating with quark-gluon plasma in strong magnetic field

Synchrotron radiation is a key feature of high-energy processes involving charged particles in magnetic fields. In compact stars and non-central nuclear collisions, the particles emitting radiation rotate with the system. In particular, the Quark-Gluon Plasma (QGP) produced in relativistic heavy-ion collisions has high vorticity and is subject to an intense magnetic field. We derive an analytical expression and perform the numerical calculations for the total radiation emitted by a rigidly rotating fermion immersed in a magnetic field. We develop the quasi-classical approximation using the WKB method and argue that it significantly improves computational performance and provides a promising framework for extending the analysis to multi-particle systems, such as those found in the QGP.
