Measurement of the Near-Threshold e+e-D(*)±D(*) Cross Section using Initial-State Radiation

We report measurements of the exclusive cross section for e+e-→DD, where D=D0 or D+, in the center-of-mass energy range from the DD threshold to 5 GeV with initial-state radiation. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 673fb-1. © 2008 The American Physical Society.
