The search for a dark photon produced at $e^{+}e^{-}$ colliders which subsequently decays into inelastic matter particles, is discussed. heavier pair of visible charged particles and lighter particle after traveling some distance. decay products can be recorded by detector made emulsions gas detectors, placed near the main detector. This setup not only explore new parameter regions reached before, but also re-open thought to excluded previous experimental data. physics potential such around BESIII Belle II presented.
