Constraints on subleading interactions in beta decay Lagrangian
Abstract We discuss the effective field theory (EFT) for nuclear beta decay. The general quark-level EFT describing charged-current interactions between quarks and leptons is matched to the nucleon-level non-relativistic EFT at the O MeV $$ \mathcal{O}\left(\textrm{MeV}\right) $$ momentum scale char...
