Abstract

Description

I outline the power counting scheme recently introduced by M. Savage, M. Wise and myself for the effective field theory treatment of nucleon-nucleon scattering. It is particularly useful for describing systems with a large scattering length, and differs from Weinberg's power counting. A renormalization group analysis plays a big role in determining the order of a given operator. Pions are ignored in this discussion; how to incorporate them is discussed in M. Savage's talk, nucl-th/9804034.
