= On shell renormalization scheme
{wiki=On_shell_renormalization_scheme}
The on-shell renormalization scheme is a method used in quantum field theory to handle the divergences that arise in the calculation of physical quantities. In this approach, the parameters of a quantum field theory, such as mass and coupling constants, are renormalized in a way that relates the theoretical predictions directly to measurable physical quantities, specifically the observables associated with actual particles.
