Renormalization schemes and the range of two-nucleon effective field theory
- California Institute of Technology, Pasadena, California 91125 (United States)
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 NN scattering data are performed in the {sup 1}S{sub 0} and {sup 3}S{sub 1} channels for different values of {mu}{sub R}. An error analysis indicates that the range of the theory with perturbative pions is consistent with 500 MeV. {copyright} {ital 1999} {ital The American Physical Society}
