Muon capture in hydrogen

Abstract

Theoretical difficulties in reconciling the measured rates for ordinary and radiative muon capture are discussed, based on heavy-baryon chiral perturbation theory. We also examine ambiguity in our analysis due to the formation of p$\mu$p molecules in the liquid hydrogen target.
