讲座内容：

The newly discovered and the previously observed provide us with a good opportunity to study the light hybrid nonet. we use a semirelativistic quark potential model to study the masses of the light hybrid states, where the static potential for depicting the confinement force between the quark-antiquak pair in a hybrid system is borrowed from the SU(3) lattice gauge theory. We also employ a constituent gluon model to analyze the strong decay behaviour of these light hybrids. Our result suggests that the and could be the candidates of and hybrids, respectively. For completeness, we study the isospin partners of the and in the nonet, i.e. the and states. The promising decay channels to find them are suggested for experiments.
