Abstract

We have measured the cross-section ratio

R = \frac{σ (ν p π^{-})}{σ (μ^{-} p π^{+})} = 0.11 \pm 0.023, 0.13 \pm 0.023, 0.15 \pm 0.025

for

M_{p π} < 1.4, 1.6, 2.0

GeV, respectively, in the energy range

0.4 < E_{ν} < 3.0

GeV. The data are consistent with various weak one-pion production models incorporating the Weinberg-Salam structure of neutral currents.
