Abstract

We use a detailed dispersion-theoretic model for pion production in the (3, 3)-resonance region to calculate the ratio

R = \frac{σ (ν_{μ} + n \to ν_{μ} + n + π^{0}) + σ (ν_{μ} + p \to ν_{μ} + p + π^{0})}{2 σ (ν_{μ} + n \to μ^{-} + p + π^{0})}

in the Weinberg weak-interaction theory. We find that

I = \frac{1}{2}

contributions do not substantially modify the earlier static model calculation of

R

given by B. W. Lee.
