摘要
We discuss recent measurements of exclusive e^+e^- cross sections for charmed hadron final states near threshold performed by Belle and BABAR. The results are based on a study of events with initial-stateradiation photons in a large data sample collected with the Belle and BABAR detectors at the T(4S) resonance and nearby continuum.
