Bound and Resonant Spectra of Few-Lepton Coulomb Systems

Liang-Zhen Wen, Yao Ma, Zhi-He Shen +1

We present a unified calculation of bound and resonant states in purely leptonic Coulomb systems: $e^{-}{e}^{-}{e}^{+}$ (${\mathrm{Ps}}^{-}$), ${\mu }^{+}{e}^{-}{e}^{-}$ (${\mathrm{Mu}}^{-}$), ${\mu }^{+}{\mu }^{+}{e}^{-}$ ($\mathr…
