Triton binding energy with realistic statistical uncertainties

We compute the binding energy of triton with realistic statistical errors stemming from NN scattering data uncertainties and the deuteron and obtain Et = −7.638(15) MeV. Setting the numerical precision as Enum t 1 keV we obtain the statistical error Estat t = 15(1) keV which is mainly determined by the channels involving relative S waves. This figure reflects the uncertainty of the input NN data, more than two orders of magnitude larger than the experimental precision E t = 0.1 keV, and sets a limit on the realistic precision that can be reached. This suggests an important reduction in the numerical precision and hence in the computational effort.
