Measurement of e +e -→Ds(*)+Ds(*)- cross sections near threshold using initial-state radiation
We report a measurement of exclusive e⊃+e⊃-→Ds(*)+D s(*)- cross sections as a function of center-of-mass energy near the Ds(*)+Ds(*)- threshold with initial-state radiation. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 967fb⊃-1. © 2011 The American Physical Society.
