Radiative Neutron β-Decay in Effective Field Theory

We consider radiative β-decay of the neutron in heavy baryon chiral perturbation theory. Nucleon-structure effects not encoded in the weak coupling constants g(A) and g(V) are determined at next-to-leading order in the chiral expansion, and enter at the [Formula: see text]-level, making a sensitive...

Nucleon-structure effects not encoded in the weak coupling constants g(A) and g(V) are determined at next-to-leading order in the chiral expansion, and enter at the [Formula: see text]-level, making a sensitive test of the Dirac structure of the weak currents possible.
