Superfield perturbation theory and renormalization
journal contributionposted on 2023-05-18, 05:26 authored by Robert DelbourgoRobert Delbourgo
The perturbation theory graphs and divergences in supersymmetric Lagrangian models are studied by using superfield techniques. In superΦ 3-theory very little effort is needed to arrive at the single infinite (wave function) renormalization counter-term, while inΦ 4-theory the method indicates the counter-Lagrangians needed at the one-loop level and possibly beyond.
