Abstract

It is commonly assumed that the leakage terms in the Fubini-Furlan sum rule for the $K_{l 3}$ scalar form factor $F (t)$ either are very small or are dominated by contributions from uncharged intermediate states. We show that these assumptions are incompatible with results for $F (t)$ based on approximate chiral symmetry.
