Sensitivity of beta - gamma circular polarization measurements to a possible right-handed current presence in the weak interaction.

Abstract

The description of \ensuremath{\beta}-\ensuremath{\gamma} (circular polarization) correlations in the allowed decay of unoriented nuclei is extended to include possible right-handed currents within a partity symmetric model of weak interactions assuming manifest symmetry and essentially massless Dirac neutrinos. The result is of sensitivity generally equal to that of \ensuremath{\beta} polarization and asymmetry determinations. Present experiments are, however, insufficiently precise to permit the extraction of new information on their existence.
