Abstract
The K ∗ → Kππ rate is calculated using vector meson pole dominance in several recent coupling-constant models. Including the effects of the contact interaction, the various models give results ranging from 8 to 86 keV for the decay rate. Taking the ω → 3π and ø → 3π decays into accont, we believe the result of 50 keV to be more reliable upper bound. This is significantly higher than older estimates and within the realm of experimental measurement.
