Abstract
We report measurements of meson decays to two kaons using of data collected with the Belle detector at the KEKB energy-asymmetric collider. We find evidence for signals in and with significances of and , respectively. (Charge-conjugate modes are included.) The corresponding branching fractions are measured to be and . These decay modes are examples of hadronic transitions. No signal is observed in the decay , and we set an upper limit of at 90% confidence level.
