Measurement of the Cross Section at Center-of-Mass Energies from 4.699 to 4.951 GeV and Search for in the Decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +651
We perform the first investigation of the process and report its Born cross sections over a range of center-of-mass energies from 4.699 to 4.951~GeV. Th…
