Y(2175): Distinguish Hybrid State from Higher Quarkonium

Abstract

The possibility of Y(2175) as a $2{}^3{D}_1$ $s\bar{s}$ meson is studied. We study the decay of $2{}^3{D}_1$ $s\bar{s}$ from both the ${}^3{P}_0$ model and the flux tube model, and the results are similar in the two models. We show that the decay patterns of $1^{--}$ strangeonium hybrid and $2{}^3{D}_1$ $s\bar{s}$ are very different. The experimental search of the decay modes $KK$, $K^{\ast }{K}^{\ast }$, $K(1460)K$, $h_1(1380)\eta$ is suggested to distinguish the two pictures. Measuring the $K^{\ast }{K}^{\ast }$ partial width ratios is crucial to discriminate the $2{}^3{D}_1$ from the $3{}^3{S}_1$ $s\bar{s}$ assignment.
