Abstract
We present an analysis of the effects of asymptotic freedom on charged current ν and ν deep inelastic scattering. We consider both the GIM model and the five-quark model with right-handed couplings. We calculate the Q 2 dependence of the quark distributions as given by asymptotic freedom, and we use these distributions to calculate σ ν /σ ν, 〈y〉 ν as well as x and y distributions. We study the effects of asymptotic freedom in charm and b quark production. We also discuss the sensitivity of our results to the shape of the gluon distribution. We emphasize the importance of comparing theory with data excluding low Q 2 values (say Q 2 ⩾ 2 GeV 2) in attempting to resolve the high y anomaly controversy.
