Measurement of ${\chi }_{cJ}$ decaying into ${\eta }^{\prime }{K}^{+}{K}^{-}$

Abstract

Using $(106.41\pm 0.86)\times 10^6$ $\psi (3686)$ events collected with the BESIII detector at BEPCII, we study for the first time the decay ${\chi }_{cJ}\to {\eta }^{\prime }{K}^{+}{K}^{-}$, where ${\eta }^{\prime }\to \gamma {\rho }^0$ and ${\eta }^{\prime }\to \eta {\pi }^{+}{\pi }^{-}$. A partial wave analysis in the covariant tensor amplitude formalism is performed for the decay ${\chi }_{c1}\to {\eta }^{\prime }{K}^{+}{K}^{-}$. Intermediate processes ${\chi }_{c1}\to {\eta }^{\prime }{f}_0(980)$, ${\chi }_{c1}\to {\eta }^{\prime }{f}_0(1710)$, ${\chi }_{c1}\to {\eta }^{\prime }{f}_2^{\prime }(1525)$ and ${\chi }_{c1}\to K_0^{\ast }(1430{)}^{\pm }{K}^{\mp }$ ($K_0^{\ast }(1430{)}^{\pm }\to {\eta }^{\prime }{K}^{\pm }$) are observed with statistical significances larger than 5$\sigma$, and their branching fractions are measured.
