Hard-Region Fermion Self-Energy and Fermion--Photon Vertex in Thermal QED through Two Loops
Ali Hataei
In massless thermal QED in a general covariant gauge, we compute hard-region contributions to the fermion self-energy and the off-shell fermion--photon vertex at one-loop ne…

Kinetic Theory of Quasiparticles, Retarded Correlators and Hydrodynamics
Ali Hataei, Roya Heydari, Farid Taghinavaz
Within the relaxation time approximation under a constant mass profile, we investigate the collective dynamics of a system of massive relativistic particles described by the Maxwel…

Thermal Fermion Propagators and Flavor-Changing via Loop Corrections in the Early Universe
A. Hataei, S. S. Gousheh
We present the Minimally Extended Standard Model in the mass basis in the symmetric phase of the early Universe, demonstrating that the CP-violating CKM and PMNS matrices emerge no…
