Query: A Novel Regularization Scheme for Nucleon-Nucleon Lattice Simulations
  with Effective Field Theory   We propose a new regularization scheme to study the bound state of
two-nucleon systems in Lattice Effective Field Theory. Inspired by continuum
EFT calculation, we study an exponential regulator acting on the leading-order
(LO) and next-to-leading order (NLO) interactions, consisting of local contact
terms. By fitting the low-energy coefficients (LECs) to deuteron binding energy
and the asymptotic normalization coefficient (ANC) on a lattice simulation, we
extract the effective range expansion (ERE) parameters in the $^3S_1$ channel
to order $p^2$. We explore the impact of different powers of the regulator on
the extracted ERE parameters for the lattice spacing $a=1.97$ fm. Moreover, we
investigate how the implementation of the regularization scheme improves the
predicted ERE parameters on the lattice spacing in the range of $1.4 \le a \le
2.6$ fm. Our numerical analysis indicates that for lattice spacing greater than
$2$ fm, the predicted observables are very close to the experimental data.
