Recent theoretical results on |Delta I|=3/2 decays of hyperons
Abstract
Description
We present a discussion of the |Delta I|=3/2 amplitudes of the hyperon decays B->B'+pi in the context of chiral perturbation theory. We evaluate the theoretical uncertainty of the lowest-order predictions by calculating the leading non-analytic corrections. We find that the corrections to the lowest-order predictions are within the expectations of naive power-counting and, therefore, that this picture can be examined more quantitatively with improved measurements.
