Renormalization schemes and the range of two-nucleon effective field theory

Abstract

The off-shell momentum subtraction (OS) and power divergence subtraction (PDS) renormalization schemes for the effective field theory with nucleons and pions are investigated. We explain in detail how the renormalization is implemented using local counterterms. Fits to the [Formula Presented] scattering data are performed in the [Formula Presented] and [Formula Presented] channels for different values of [Formula Presented] An error analysis indicates that the range of the theory with perturbative pions is consistent with [Formula Presented]. © 1999 The American Physical Society.
