True Leptonium ( $l^{+} l^{-}$ ) Production in UPC Triphoton Interaction

Qi-Ming Feng, Qi-Wei Hu, Cong-Feng Qiao

True leptonium states ( $l^{+} l^{-}$ ) are compact pure QED systems, first theoretically predicted eight decades ago. Although considerable efforts have been devoted to their search, on…

QCD sum rule predictions on gluonic tetraquark states with $J^{P C} = 0^{+-}, 0^{--}$ and $1^{\pm\pm}$

Chun-Meng Tang, Chun-Gui Duan, Liang Tang +1

In this work, we present a systematic calculation of the mass spectrum for tetraquark hybrid states, focusing on the $8_{[c c ˉ]} \otimes 8_{[G]} \otimes 8_{[c c ˉ]}$ color con…

A novel configuration of gluonic tetraquark state

Chun-Meng Tang, Chun-Gui Duan, Liang Tang +1

Inspired by the experimental measurement of the charmed hadronic state X(6900), we calculate the mass spectra of tetraquark hybrid states with configuration of \([8_{c}]_{Q\bar{Q}}…
