Abstract

Based on the notions of chiral dynamics and the field-current identity as applied to the broken SU(3), theoretical expressions for the form factors

f_{\pm} (t)

are obtained. A small

ξ

(

| ξ | ≪ 1

) and a large

| λ_{-} |

(an order of magnitude larger than

λ_{+}

) are predicted. [However, the product

ξ λ_{-}

is expected to be small.]
