摘要：
We propose a non-perturbative renormalization procedure for light-front Hamiltonian. Wilson's renormalization group prescription is applied to lambda phi(4)-model within a light-front Fock space truncated up to three-body state. Renormalized Hamiltonian which preserves low-energy physics for arbitrary renormalization transformations is presented. Renormalization group equations for mass parameter mu(2) and coupling constant lambda are derived by integrating high invariant mass space and rescaling transverse momenta and fields.
