Abstract
We report measurements of the exclusive cross section for as a function of center-of-mass energy from the threshold to 5.2 GeV with initial-state radiation. No evidence is found for decays. The analysis is based on a data sample collected with the Belle detector at or near a center-of-mass energy of 10.58 GeV with an integrated luminosity of at the KEKB asymmetric-energy collider.
