Description
With 10 billion Jpsi events, 2.7 billion psi(3686) events, and about 25 fb-1 scan samples taken at center of mass energies from 3.7 to 4.95 GeV, the dark photon produced in e+e- annihilation or hadron decay processes have been studied at BESIII. In this talk, we report the search for invisible dark photon using initial state radiation process, Jpsi Dalitz decays, and baryon decays.
