A New Approach to Effective Field Theory for Few-Nucleon Physics

ORAL

Abstract

I describe an alternate formulation of the effective field theory expansion for nucleon-nucleon interactions, which is a hybrid between the approach of Weinberg and that of Kaplan, Savage and Wise (KSW). Like the KSW approach, pion exchange is treated perturbatively, and amplitudes may be computed analytically, yet without the convergence problems previously caused by the tensor force.
