Renormalization of EFT for nucleon-nucleon scattering
arXiv:nucl-th/0407090
Abstract
The renormalization of EFT for nucleon-nucleon scattering in nonperturbative regimes is investigated in a compact parametrization of the -matrix. The key difference between perturbative and nonperturbative renormalization is clarified. The underlying theory perspective and the 'fixing' of the prescriptions for the -matrix from physical boundary conditions are stressed.
