Description
We present a new lattice formulation of chiral effective nuclear force with simpler
decomposition into partial waves. With these new interactions the process of fitting
to the empirical-observed scattering phase shifts is simplified, and the resulting
lattice phase shifts are more accurate than those in precious studies. We present results
for neutron-proton system up to next-to-next-to-next-to-leading order with lattice spacings of 1.97 fm, 1.64fm, 1.32fm and 0.99fm. We also present the new lattice results for the spectrum of the light and medium mass nuclei calculated with these new interactions
