Infrared and extended on-mass-shell renormalization of two-loop diagrams
arXiv:hep-ph/0310207 · doi:10.1016/j.nuclphysb.2004.01.027
Abstract
Using a toy model Lagrangian we demonstrate the application of both infrared and extended on-mass-shell renormalization schemes to multiloop diagrams by considering as an example a two-loop self-energy diagram. We show that in both cases the renormalized diagrams satisfy a straightforward power counting.
