One-Nucleon Effective Generators of the Poincare Group derived from a Field Theory: Mass Renormalization
A. Kruger, W. Glockle
Abstract
We start from a Lagrangian describing scalar "nucleons" and mesons which interact through a simple vertex. Okubo's method of unitary transformation is used to describe a single nucleon dressed by its meson cloud. We find an expression for the physical mass of the nucleon being correct up to second order in the coupling constant. It is then verified that this result is the same as the corresponding expression found by Feynman techniques. Finally we also express the three boost operators in terms of the physical nucleon mass. Doing so we find expressions for all the ten generators of Poincaré transformations for the system of one single dressed nucleon.
