Title Partial muon capture rates in A = 3 and A = 6 nuclei with chiral effective field theory
Abstract Searches for neutrinoless-double beta decay rates are crucial in addressing questions within fun- damental symmetries and neutrino physics. The rates of these decays depend not only on unknown parameters associated with neutrinos, but also on nuclear properties. In order to reliably extract in- formation about the neutrino, one needs an accurate treatment of the complex many-body dynamics of the nucleus. Neutrinoless-double beta decays take place at momentum transfers on the order of 100 MeV/c and require both nuclear electroweak vector and axial currents. Muon capture, a process in the same momentum transfer regime, has readily available experimental data to validate these currents. In this work, we present results of ab initio calculations of partial muon capture rates for 3He and 6Li nuclei using variational and Green?s Function Monte Carlo computational methods. We estimate the impact of the three-nucleon interactions, the cutoffs used to regularize two-nucleon (2N) interactions, a
