Regularization and renormalization in effective field theories of the nucleon - nucleon interaction
Some form of nonperturbative regularization is necessary if effective field theory treatments of the NN interaction are to yield finite answers. We discuss various regularization schemes used in the literature. Two of these methods involve formally iterating the divergent interaction and then regularizing and renormalizing the resultant amplitude. Either a (sharp or smooth) cutoff can be introd...
متن کاملNucleon-Nucleon Scattering from Effective Field Theory
We perform a nonperturbative calculation of the S0 NN scattering amplitude, using an effective field theory (EFT) expansion. We use dimensional regularization throughout, and the MS renormalization scheme; our final result depends only on physical observables. We show that the EFT expansion of the quantity |p| cot δ(p) converges at momenta much greater than the scale Λ that characterizes the de...
متن کاملSubtractive renormalization of chiral effective theory NN potentials up to next-to-next-to-leading order
We have developed a subtractive renormalization method with which we can evaluate nucleonnucleon (NN) scattering phase shifts produced by the NN potential obtained at leading, nextto-leading, and next-to-next-to-leading order (NNLO) in chiral effective theory (χET). In this method the low-energy constants associated with short-distance NN physics are eliminated from the Lippmann-Schwinger equat...

متن کاملPower Counting and the Renormalization Group for an Effective Description of NN Scattering
I outline the power counting scheme recently introduced by M. Savage, M. Wise and myself for the effective field theory treatment of NN scattering. It is particularly useful for describing systems with a large scattering length, and differs from Weinberg’s power counting. A renormalization group analysis plays a big role in determining the order of a given operator. Pions are ignored in this di...
