Query: Toward a resolution of the NN controversy   Lattice QCD calculations of two-nucleon interactions have been underway for
about a decade, but still haven't reached the pion mass regime necessary for
matching onto effective field theories and extrapolating to the physical point.
Furthermore, results from different methods, including the use of the Luscher
formalism with different types of operators, as well as the HALQCD potential
method, do not agree even qualitatively at very heavy pion mass. We investigate
the role that different operators employed in the literature may play on the
extraction of spectra for use within the Luscher method. We first explore
expectations from Effective Field Theory solved within a finite volume, for
which the exact spectrum may be computed given different physical scenarios. We
then present preliminary lattice QCD results for two-nucleon spectra calculated
using different operators on a common lattice ensemble.
