Abstract

We estimate renormalization effects on

\frac{σ_{\bar{ν}}}{σ_{ν}}

and

{〈 y 〉}_{\bar{ν}}

in the standard four-quark model, improving on a calculation by Altarelli, Petronzio, and Parisi. Even with systematic overestimates, the Weinberg-Salam model does not give a satisfactory account of the data.
