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…

Singly heavy tetraquark resonant states with multiple strange quarks

Xin-He Zheng, Yao Ma, Shi-Lin Zhu

We systematically investigate the S-wave singly heavy tetraquark systems containing two or three strange quarks, $Q s s ˉ s ˉ$ , $Q n s ˉ s ˉ$ and $Qs\bar{s}\bar{n}\left(…

Tetraquark states in the quark model

Wei-Lin Wu, Yan-Ke Chen, Yao Ma +2

We perform systematical investigations of heavy flavor tetraquark systems, including fully heavy $QQ Q ˉ Q ˉ$ ( $Q = b, c$ ), doubly heavy $Q Q^{(')} q ˉ q ˉ$ ( $q = u, d$ ), and…

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 =…

The $I ¨ N N, J / I ¨ N N, I^\cdot_{c} N N$ systems based on HAL QCD interactions

Liang-Zhen Wen, Yao Ma, Lu Meng +1

We investigate the existence of bound states and resonances in the $I ¨ N N, J / I ¨ N N, I^\cdot_{c} N N$ systems using HAL QCD interactions for $I ¨ N, J / I ¨ N$ , and $I^\cdot_{c} N$ . We employ the Ga…

Constraining the $D D D^{*}$ three-body bound state via the $Z_{c} (3900)$ pole

Hai-Xiang Zhu, Lu Meng, Yao Ma +3

In this study, we propose using the $Z_{c} (3900)$ pole position to constrain the existence of the $D D D^{*}$ three-body bound state within the one-boson-exchange (OBE) model. The existe…
