Renormalized nonperturbative fermion model in covariant light-front dynamics
Renormalized nonperturbative fermion model in covariant light-front dynamics
Within the framework of the covariant formulation of Light-Front Dynamics, we develop a nonperturbative renormalization scheme in the fermion model supposing that the composite fermion is a superposition of the "bare" fermion and a fermion+boson state. We first assume the constituent boson to be spinless. Then we address the case …
