Abstract
We report a new measurement of the exclusive cross sections as a function of the center-of-mass energy from the threshold through GeV with initial-state radiation. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of fb. The accuracy of the cross section measurement is increased by a factor of two over the first Belle study. We perform the first angular analysis of the process and decompose this exclusive cross section into three components corresponding to the helicities.
