Abstract: (APS)
The cross sections of the process at center-of-mass energies from 3.508 to 4.951 GeV are measured with high precision using data collected with the BESIII detector operating at the BEPCII storage ring. The cross sections are of the order of a few picobarn and decrease as the center-of-mass energy increases as with . This result is in agreement with the Nambu-Jona-Lasinio model prediction of . In addition, the charmless decay is searched for by fitting the measured cross sections, yet no significant signal is observed. The upper limit of at the 90% confidence level is determined to be .- electron positron: annihilation
- electron positron: colliding beams
- Phi(1020): electroproduction
- eta(958): electroproduction
- channel cross section: measured
- energy dependence
- psi(3770): hadronic decay
