Abstract: (APS)
The decay process KL→π0π∓e±{(−)}{ν} is studied in the vector-meson-dominance framework in the hidden symmetry scheme. We find that vector symmetry in KL→π−π∓e±{(−)}{ν} is far from the real world. The inclusion of vector mesons generates an mππ dependence of the F2−0 form factor, and thus improves the lowest-order prediction of the chiral Lagrangian. Also, our model predicts B(KL→π0π∓e±{(−)}{ν})=5.2×10−5. We also give a brief discussion of Kl3 in the same model.- K0(L): semileptonic decay
