Hyperon radiative decay
Abstract
The radiative decay widths of the low-lying strange baryons are calculated both within the relativistic quark bag model and the nonrelativistic potential model. These widths are found to depend sensitively upon the quark-model dynamics through multiplet mixing and q4q-bar admixtures. The comparison between our calculated results and the very limited experimental data is discussed.
