Nucleon-Nucleon Scattering from Fully Dynamical Lattice QCD

We present results of the first fully dynamical lattice QCD determination of nucleon-nucleon scattering lengths in the ${}^{1}S_0$ channel and ${}^{3}S_1-{}^{3}D_1$ coupled channels. The calculations are performed with domain-wall valence quarks on the MILC staggered configurations with a lattice spacing of $b=0.125\mathrm{fm}$ in the isospin-symmetric limit, and in the absence of electromagnetic interactions.
