Singly heavy tetraquarks

Jun-Jie Liu, Zhi-Biao Liang, Feng-Xiao Liu +3

In this work, we carry out a systematic study of the spectra of the $1 S$ -wave states for the whole singly-heavy tetraquark systems within a semi-relativistic hybrid quark potential…

Fully-strange tetraquarks: fall-apart decays and experimental candidates

Feng-Xiao Liu, Xian-Hui Zhong, Qiang Zhao

We presents a systematic analysis of the fall-apart decays for the $1 S$ , $1 P$ , and $2 S$ -wave fully-strange tetraquark states. It shows that most of the fully-strange tetraquark sta…

Study of the $e^{+} e^{-} \to J / ψ π^{+} π^{-}$ lineshape near the $D^{*} D ˉ + c . c .$ threshold and possible signals for exotic hidden charm states

Jun Wang, Qiang Zhao

We investigate the lineshape of the $e^{+} e^{-} \to J / ψ π^{+} π^{-}$ cross section in the vicinity of the $D^{*} D ˉ + c . c .$ threshold, where the ``so-called'' $G (3900)$ is observe…

Decoding spin-parity quantum numbers and decay widths of double $J / I ¨ $ exotic states

Kaiwen Chen, Feng-Xiao Liu, Qiang Zhao +3

We derive helicity amplitudes for the fully charmed tetraquark states decays into vector meson pair under two types of models, where the one is from quark model and the other one i…
