A new expansion for nucleonnucleon interactions
Abstract
We introduce a new and well defined power counting for the effective field theory describing nucleonnucleon interactions. Because of the large NN scattering lengths it differs from other applications of chiral perturbation theory and is facilitated by introducing an unusual subtraction scheme and renormalization group analysis. Calculation to subleading order in the expansion can be done analytically, and we present the results for both the ^{1}S_{0} and ^{3}S_{1}^{3}D_{1} channels.
