A Nonperturbative Renormalization Group Procedure for Light-Front Hamiltonian
Takanori Sugihara, Masanobu Yahiro · Progress of Theoretical Physics Supplement · 1995
We propose a non-perturbative renormalization procedure for light-front Hamiltonian. Wilson's renormalization group prescription is applied to ..1<,64-model within a light-front Fock space truncated up to three-body state. Renormalized Hamiltonian which preserves lowenergy physics for arbitrary renormalization transformations is presented. Renormalization group equations for mass parameter tl and coupling constant A are derived by integrating high invariant mass space and rescaling transverse momenta and fields.
