    Abstract:
    We compute the branching ratio for Ne+e- and N+- in chiral perturbation theory and find that both decays should be observable at the Continuous Electron Beam Accelerator Facility. With sufficiently low thresholds on the e+e- invariant mass a branching ratio of 10-5 may be observed for Ne+e-. For the N+- decay mode we predict a branching ratio of 3×10-7. The dependence of the M1 and E2 amplitudes on the momentum transfer will provide a useful test of chiral perturbation theory which predicts 20% variation over the allowed kinematic range. © 1993 The American Physical Society.
