Convergent perturbation expressions and analyticity properties in static field-theoretic models
Simplified field-theoretic models, consisting of a charged-pion field coupled linearly and quadratically to a fixed extended nucleon with spin and isospin, are considered. For small couplings it is shown that perturbation theory converges and yields the dressed one-nucleon states and the resolvent o...
