Abstract

We report measurements of the exclusive cross section for e+e-→D0D*-π+ as a function of center-of-mass energy from the D0D*-π+ threshold to 5.2 GeV with initial-state radiation. No evidence is found for Y(4260)→D0D*-π+ decays. The analysis is based on a data sample collected with the Belle detector at or near a center-of-mass energy of 10.58 GeV with an integrated luminosity of 695fb-1 at the KEKB asymmetric-energy e+e- collider.
