Title Muon capture on deuteron using local chiral potentials
Abstract The muon capture reaction µ - + d ¿ n + n + ¿µ in the doublet hyperfine state is studied using nuclear potentials and consistent currents derived in chiral effective field theory, which are local and expressed in coordinate-space (the so-called Norfolk models). Only the largest contribution due to the 1S0 nn scattering state is considered. Particular attention is given to the estimate of the theoretical uncertainty, for which four sources have been identified: (i) the model dependence, (ii) the chiral order convergence for the weak nuclear current, (iii) the uncertainty in the single-nucleon axial form factor, and (iv) the numerical technique adopted to solve the bound and scattering A = 2 systems. This last source of uncertainty has turned out essentially negligible. The 1S0 doublet muon capture rate GD(1S0) has been found to be GD(1S0) = 255.8(0.6)(4.4)(2.9) s-1, where the three errors come from the first three sources of uncertainty. The value for GD(1S0) obtained within t
