Angular analysis of the e+e- → D(*)D* process near the open-charm threshold using initial-state radiation

Angular analysis of the e+e- → D(*)D* process near the open-charm threshold using initial-state radiation

We report new measurement of the exclusive e+e- → D(*)±D*∓ cross sections as a function of center-of-mass energy from the D(∗)±D∗∓ threshold up to s$ \sqrt s $ = 6.0 GeV with initial state radiation. The analysis is based on a data sample collected by the Belle detector with an integrated luminosity...
