dc.description.abstract | Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e+e-???cJ (J=0, 1, 2). The process e+e-???c0 is observed for the first time, and the Born cross sections at s=4.23 and 4.26 GeV are measured to be (55.4±6.0±5.9) and (23.7±5.3±3.5)pb, respectively, where the first uncertainties are statistical and the second are systematic. The ??c0 signals at the other seven energies and the e+e-???c1 and ??c2 signals are not significant, and the upper limits on the cross sections are determined. By examining the ??c0 cross section as a function of center of mass energy, we find that it is inconsistent with the line shape of the Y(4260) observed in e+e-??+?-J/?. Assuming the ??c0 signals come from a single resonance, we extract the mass and width of the resonance to be (4230±8±6)MeV/c2 and (38±12±2)MeV, respectively, and the statistical significance is more than 9?. © 2015 American Physical Society. | en_US |
