Nucleon-Nucleon Scattering from Fully Dynamical Lattice QCD

Abstract

We present results of the first fully dynamical lattice QCD determination of nucleon-nucleon scattering lengths in the $^{1}S_{0}$ channel and $^{3}S_{1}\ensuremath{-}^{3}D_{1}$ coupled channels. The calculations are performed with domain-wall valence quarks on the MILC staggered configurations with a lattice spacing of $b=0.125\text{ }\text{ }\mathrm{fm}$ in the isospin-symmetric limit, and in the absence of electromagnetic interactions.
