Abstract

The data on $J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\gamma}{K}^{+}{K}^{\ensuremath{-}}$ from the BES experiment at the Beijing electron-positron collider have been analyzed. We find two resonances in the 1.7 GeV region which were identified as ${f}_{J}(1710)$: a scalar with mass $1781\ifmmode\pm\else\textpm\fi{}{8}_{\ensuremath{-}31}^{+10}(\mathrm{MeV})$ and width $85\ifmmode\pm\else\textpm\fi{}{24}_{\ensuremath{-}19}^{+22}(\mathrm{MeV})$, and a tensor with mass $1696\ifmmode\pm\else\textpm\fi{}{5}_{\ensuremath{-}34}^{+9}(\mathrm{MeV})$ and width $103\ifmmode\pm\else\textpm\fi{}{18}_{\ensuremath{-}11}^{+30}(\mathrm{MeV})$. The resulting branching ratios $B(J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\gamma}{f}_{J})B({f}_{J}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}})$ are ( $0.8\ifmmode\pm\else\textpm\fi{}{0.1}_{\ensuremath{-}0.1}^{+0.3}){10}^{\ensuremath{-}4}$ for $J\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$ and ( $2.5\ifmmode\pm\else\textpm\fi{}{0.4}_{\ensuremath{-}0.4}^{+0.9}){10}^{\ensuremath{-}4}$ for $J\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2$, respectively.
