Partial Wave Analysis of ${\chi }_{c0}\to {\pi }^{+}{\pi }^{-}{K}^{+}{K}^{-}$

M. Ablikim, BES Collaboration

A partial wave analysis of ${\chi }_{c0}\to {\pi }^{+}{\pi }^{-}{K}^{+}{K}^{-}$ in $\psi (2S)\to \gamma {\chi }_{c0}$ decay is presented using a sample of 14 million $\psi (2S)$ events accumulated by the BES II detector. The data…
