Theoretical studies of muon capture on light nuclei

Abstract

We review the present status of theoretical studies of muon capture reactions on light nuclei. In particular we consider the two reactions 2 H(µ − , ν µ)nn and 3 He(µ − , ν µ) 3 H, and the most recent calculations performed within the chiral effective field theory framework. The unresolved discrepancies among the different calculations and future developments are also discussed.
