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…

Running coupling constant in thermal theory up to two loop order
K. Arjun, A. M. Vinodkumar, Vishnu Mayya Bannur
Using the imaginary time formalism in thermal field theory, we derive running coupling constant and running mass in two loop order. In the process, we express the imaginary time fo…
