Light double-gluon hybrid states from QCD sum rules

Niu Su, Hua-Xing Chen, Wei Chen +1

We study the double-gluon hybrid states with the quark-gluon contents $q ˉ q g g$ ( $q = u / d$ ) and $s ˉ s g g$ . We construct twelve double-gluon hybrid currents with various quant…

Highly excited and exotic fully-strange tetraquark states

Rui-Rui Dong, Niu Su, Hua-Xing Chen

Some hadrons have the exotic quantum numbers that the traditional $q ˉ q$ mesons and $q q q$ baryons can not reach, such as $J^{P C} = 0^{--} / 0^{+-} / 1^{-+} / 2^{+-} / 3^{-+} / 4^{+-}$ , e…

$S$ - and $P$ -wave fully-strange tetraquark states from QCD sum rules

Niu Su, Hua-Xing Chen

We apply the QCD sum rule method to systematically study the $S$ - and $P$ -wave fully-strange tetraquark states within the diquark-antidiquark picture. We systematically construct t…

QCD axial anomaly enhances the $η η^{'}$ decay of the hybrid candidate $η_{1} (1855)$

Hua-Xing Chen, Niu Su, Shi-Lin Zhu

We study the hybrid mesons with the exotic quantum number $I^{G} J^{P C} = 0^{+} 1^{-+}$ and investigate their decays into the $η η^{'}$ , $a_{1} (1260) π$ , $f_{1} (1285) η$ , $f_{1} (1420) η$ , $K…
