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: $e^{-} e^{-} e^{+}$ ( $Ps^{-}$ ), $μ^{+} e^{-} e^{-}$ ( $Mu^{-}$ ), $μ^{+} μ^{+} e^{-}$ ($\mathr…

Heavy flavored hydrogen molecule systems

Hui-Min Yang, Yao Ma, Shi-Lin Zhu

This study provides a comprehensive analysis of $S$ -wave exotic hydrogen-like three-body systems ( $pp I^¼^{-}$ , $pp I ¨ ^{-}$ , $I^¼^{-} I^¼^{-} p$ , $I ¨ ^{-} I ¨ ^{-} p$ , $p I^¼^{-} I ¨ ^{-}$ ) with spin-parity $J^P =…
