Convergence Issues in NucleonNucleon Effective Field Theory
Abstract
The origin of the breakdown scale in an effective field theory treatment of nuclear forces is investigated. Different organizational schemes used in the nonperturbative calculation of nucleonnucleon scattering seem to break down for different physical reasons. It is argued that the same physics is actually responsible, namely strong twopion exchange as also observed in the pion scalar form factor. The prospect of extending the applicability of the effective field theory beyond this breakdown point is discussed.
