Medium correction to gravitational form factors

We generalize the gravitational form factor for chiral fermion in vacuum, which reproduces well-known spin-vorticity coupling. also calculate radiative correction to factors quantum electrodynamics plasma. find two structures contributing scattering amplitude of vorticity field, one is from fermon self-energy correction, pointing suppression coupling medium; other strucutre comes graviton-fermion vertex does not adopt potential interpretation, but corresponds transition matrix element between initial and final states. Both contribute vortical effect. The net effect that enhances Our results claify relation difference perspective factors. discuss application QCD plasma, indicating might have an appreciable spin polarization heavy ion collisions.
