dc.description.abstractThe cross section of the process e(+) e(-) -> pi(+) (DD)-D-0*(-) for center-of-mass energies from 4.05 to 4.60 GeV is measured precisely using data samples collected with the BESIII detector operating at the BEPCII storage ring. Two enhancements are clearly visible in the cross section around 4.23 and 4.40 GeV. Using several models to describe the dressed cross section yields stable parameters for the first enhancement, which has a mass of 4228.6 +/- 4.1 +/- 6.3 MeV/c(2) and a width of 77.0 +/- 6.8 +/- 6.3 MeV, where the first uncertainties are statistical and the second ones are systematic. Our resonant mass is consistent with previous observations of the Y(4220) state and the theoretical prediction of a D (D) over bar (1)(2420) molecule. This result is the first observation of Y(4220) associated with an open-charm final state. Fits with three resonance functions with additional Y(4260), Y(4320), Y(4360), psi(4415), or a new resonance do not show significant contributions from either of these resonances. The second enhancement is not from a single known resonance. It could contain contributions from psi(4415) and other resonances, and a detailed amplitude analysis is required to better understand this enhancement.
