The two-nucleon problem in EFT reformulated: Pion and nucleon masses as soft and hard scales
arXiv:1301.6134
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 $^1S_0$ and $^3S_1$ scattering lengths and the deuteron binding energy at leading order.
