The two-nucleon problem in EFT reformulated: Pion and nucleon masses as soft and hard scales

Abstract

We outline the modified formulation of baryon chiral effective field theory for nucleon-nucleon scattering and discuss the issue of a possible power counting violation by the nucleon mass. We also present the results for the quark mass dependence of the ${}^1{S}_0$ and ${}^3{S}_1$ scattering lengths and the deuteron binding energy at leading order.
