摘要
We study finite-temperature effects to one-loop order in field theories by relating them to the forward scattering of thermal particles. This approach allows for an exact evaluation of all temperature-dependent contributions to the thermal self-energy in terms of generalized zeta-functions. We obtain a closed-form expression for the two-point gluon function in thermal Yang-Mills theory.
