Query: Benchmark neutrinoless double-beta decay matrix elements in a light
  nucleus   We compute nuclear matrix elements of neutrinoless double-beta decay mediated
by light Majorana-neutrino exchange in the A = 6 system. The goal is to
benchmark two many-body approaches, the No-Core Shell Model and the
Multi-Reference In-Medium Similarity Renormalization Group. We use the
SRG-evolved chiral N3LO-EM500 potential for the nuclear interaction, and make
the approximation that isospin is conserved. We compare the results of the two
approaches as a function of the cutoff on the many-body basis space. Although
differences are seen in the predicted nuclear radii, the ground-state energies
and neutrinoless double-beta decay matrix elements produced by the two
approaches show significant agreement. We discuss the implications for
calculations in heavier nuclei.
