Concept of an Electron–Positron Collider for Production and Study of the (μ$^{+}$μ$^{–}$) Bound State

The possibility of producing and studying thus far unobserved dimuonium atoms (μ+μ−) using low-energy colliding е+е− beams is considered. Possible collider implementations are discussed, processes affecting its efficiency are investigated, and its parameters are estimated. The collider can probably also be used for high-luminosity experiments on the study of π± and η mesons.
