Second Class Currents in High Energy Neutrino Reactions

Abstract

Recently Wilkinson and Alburger11 have suggested the possible existence of the second class currents in weak interactions21 -•> transforming differently from the vector and axial vector currents under G conjugation. They have investigated the ft values for the {j decay of various mirror nuclei. They have found that theft values systematically deviate from those of the corresponding mirror nuclei. If we can ignore such effects as (i) the electromagnetic and second forbidden effects, (ii) isospin mixing and (iii) binding energy effects, we have31
