| dc.description.abstract | Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of ?s = 4.23, 4.26, and 4.36 GeV, we observe e+e- ? ?+?-hc for the first time. The Born cross sections are measured and found to be about half of those of e+e-? ?+?-hcwithin less than 2?. In the ?0hc mass spectrum, a structure at 4.02 GeV/c2 is found. It is most likely to be the neutral isospin partner of the Zc(4020)± observed in the process of e+e- ? ?+?-hc being found. A fit to the ?0hc invariant mass spectrum, with the width of the Zc(4020)0 fixed to that of its charged isospin partner and possible interferences with non- Zc(4020)0 amplitudes neglected, gives a mass of (4023.9 ± 2.2 ± 3.8) MeV/c2 for the Zc(4020)0, where the first error is statistical and the second systematic. © 2014 American Physical Society. | en_US |
