International Conference on Exotic Atoms and Related Topics - EXA2017

We present the physics program of a high-luminosity low-energy $e^{+}{e}^{-}$ collider, which project is developed in BINP (Novosibirsk). The collider center-of-mass energy varies from 210 MeV up to 960 MeV. The physics program includes observaion and study of the ${\mu }^{+}m{u}^{-}$ bound state, dimuonium, measurement of effects of the final state interaction in the reactions $e^{+}{e}^{-}\to {\mu }^{+}m{u}^{-}$ and $e^{+}{e}^{-}\to {\pi }^{+}p{i}^{-}$ near thresholds, precise measurement of hadronic cross sections ($e^{+}{e}^{-}\to {\pi }^{+}p{i}^{-}$, ${\pi }^{+}p{i}^{-}\pi 0$, ${\pi }^0\gamma$ etc.), study of rare processes, in particular, observation of direct production of the pseudoscalar mesons $\eta$ and ${\eta }^{\prime }$.
