Renormalization of EFT for nucleon-nucleon scattering
J. -F. Yang
Abstract
The renormalization of EFT for nucleon-nucleon scattering in nonperturbative regimes is investigated in a compact parametrization of the T-matrix. The key difference between perturbative and nonperturbative renormalization is clarified. The underlying theory perspective and the 'fixing' of the prescriptions for the T-matrix from physical boundary conditions are stressed.
