Chiral corrections to the baryon axial currents

Chiral logarithmic corrections to the baryon axial vector currents in semileptonic hyperon decay are computed including intermediate octet and decuplet states, and it is shown that the spin- 3 2 decuplet partially cancels the large spin- 1 2 octet contribution corrections to the quark currents are a...

Description
Summary:Chiral logarithmic corrections to the baryon axial vector currents in semileptonic hyperon decay are computed including intermediate octet and decuplet states, and it is shown that the spin- 3 2 decuplet partially cancels the large spin- 1 2 octet contribution corrections to the quark currents are also computed.
