SEMILEPTONIC HYPERON DECAY - A PROBLEM FOR CHIRAL PERTURBATION-THEORY
Journal or Book Title
PHYSICS LETTERS B
We study the recently computed mk2lnm2k corrections to hyperton beta decay found in chiral perturbation theory. The inclusion of these effects is not compatible with the high precision hyperon data, yielding a fit much inferior to the standard assumption of SU(3) invariance. This incompatibility of data and theory is a problem for the application of chiral perturbation theory.
