Measurement of the e+e- --> D0D*-pi+ cross section using initial-state radiation

TL;DR

This paper measures the cross section of e+e- to D0D*-pi+ using initial-state radiation, covering energies up to 5.2 GeV, and finds no evidence of Y(4260) decays into this final state.

Contribution

First measurement of the e+e- to D0D*-pi+ cross section across a wide energy range using initial-state radiation techniques.

Findings

No evidence for Y(4260)-->D0D*-pi+ decays.

Cross section measured from threshold to 5.2 GeV.

Data collected with Belle detector at 10.58 GeV.

Abstract

We report measurements of the exclusive cross section for e+e- --> D0D*-pi+ as function of center-of-mass energy from the D0D*-pi+ threshold to 5.2 GeV with initial-state radiation. No evidence is found for Y(4260)-->D0D*-pi+ 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 695 1/fb at the KEKB asymmetric-energy e+e- collider.
