Abstract
Using annihilation data samples collected with the BESIII detector, we measure the cross sections of and at center-of-mass energies from to GeV. In addition, we search for the charmonium-like resonance decays into and , and decays into and . Corresponding upper limits are provided since no clear signal is observed.
