报告题目：Thermal effects of a massive vector boson and the corresponding applications

　　报告人：汤亦蕾 副教授（中山大学）

　　报告摘要：Usually in the literature, the behavior of a massive vector boson in the thermal plasma remains unconcerned. I studied the thermal corrections of a vector boson in the real time formalism, and applied the results in two cases, the leptogenesis induced by a electroweak scale sterile neutrino, and the freeze-in process of the dark matter mediated by a massive vector boson. In both cases, the dispersion relations of transverse/longitudinal/Goldstone degrees of freedom play important roles.
