Measurement of via initial state radiation at Belle
Abstract
We report here measurement of the cross section of between 4.0 and 5.5 GeV, based on an analysis of initial state radiation events in a data sample recorded with the Belle detector. The properties of the and states are determined. Fitting the mass spectrum of with two coherent Breit-Wigner functions, we discover two solutions with identical mass and width but different couplings to electron-positron pairs: , , , ; and and for one solution; or and for the other. Here, the first errors are statistical and the second systematic. Evidence for a charged charmoniumlike structure at is observed in the intermediate state in the decays. decays.
