    • Abstract

       

      Defining the ratiosrp =σ(vp →vx)/σ(vp →μ−x) and$$\bar r_p = \sigma (\bar \nu p \to \bar \nu x)/\sigma (\bar \nu p \to \mu ^ + x)$$ we obtain the bounds 0.28 ⩽rp ⩽ 0.61 and$$0 \cdot 15 \leqslant \bar r_p \leqslant 0 \cdot 37$$ using only the parton model and the data of CDHS group with iron target. We also give the complete set of parton-model relations which would allow the determination of all the neutral-current coupling constants from inclusive cross sections alone.
