dc.description.abstractUsing 4.7 fb-1 of e+e- collision data at center-of-mass energies from 4.661 to 4.951 GeV collected by the BESIII detector at the BEPCII collider, we observe the X(3872) production process e+e- -omega X(3872) for the first time. The significance is 7.8 sigma, including both the statistical and systematic uncertainties. The e+e- -omega X(3872) Born cross section and the corresponding upper limit at 90% confidence level at each energy point are reported. The line shape of the cross section indicates that the omega X(3872) signals may be from the decays of some nontrivial structures. DOI: 10.1103/PhysRevLett.130.151904en_US
