Abstract

It is pointed out that measurement of the ratio {ie33-1} and theV — A interference term for the high-energy inclusive processes {ie33-2} + anything ({ie33-3} is the proton-neutron average) can give an estimate of the violation of charge symmetry in these processes. We then give an expression for charge symmetry violation in terms of experimentally measured structure functions above the charm threshold for the above processes for the Salam-Weinberg model. In addition, we give predictions for the neutral current for the processes {ie33-4} + anything, below and above the charm threshold for charged currents. It is pointed out that the predictions for the neutral current below the charm threshold are the same as those due to a phenomenological neutral current withSU3 structure {ie33-5}. We use light-cone algebra to obtain our results in the scaling region.
