Self-Energy Approximation for the Running Coupling Constant in Thermal Theory using Imaginary Time Formalism
K. Arjun, A M Vinodkumar, Vishnu Mayya Bannur +1
The running coupling constant is calculated using the imaginary time formalism (ITF) of thermal field theory under the self-energy approximation. In the process, each Feynman diagr…
