Abstract
We calculate the muon capture rate on the deuteron to next-to-next-to- leading order in the pionless effective field theory. The result can be used to constrain the two-nucleon isovector axial coupling L1,A to ±2 fm3 if the muon capture rate is measured to the 2% level. From this, one can determine the neutrino-deuteron breakup reactions and the pp fusion cross section in the sun to the same level of accuracy. © 2005 The American Physical Society.
