Abstract
We propose a new approach to treat the nucleon structure in terms of an effective chiral Lagrangian. We formulate the state vector, f(p), of the nucleon in light-front dynamics, and solve the eigenvalue equation ˆ P 2 f(p) = M 2 f(p) in a truncated Fock space. The effective Lagrangian is decomposed in terms of pion fields in order to match the Fock expansion of the state vector. We use a general renormalization scheme consistent with Fock state truncation. We present our first results in a two-body Fock space truncation.
