Effective Field Theory of Nucleon-Nucleon Scattering on Large Discrete Lattices
Ryoichi Seki, U. van Kolck
Abstract
Nuclear effective field theory is applied to the effective range expansion of S-wave nucleon-nucleon scattering on a discrete lattice. Lattice regularization is demonstrated to yield the effective range expansion in the same way as in the usual continuous open space. The relation between the effective range parameters and the potential parameters is presented in the limit of a large lattice.
