Search for the pentaquark state in ψ(2S) and J/ψ decays to KS0pK−n and KS0p¯K+n
J. Z. Bai, Y. Ban, J. G. Bian, X. Cai et autres
Results are presented on $\ensuremath{\psi}(2S)$ and $J/\ensuremath{\psi}$ hadronic decays to ${K}_{S}^{0}{\mathrm{pK}}^{\ensuremath{-}}\mathrm{n\ifmmode \bar{}\else \={}\fi{}}$ and ${K}_{S}^{0}\overline{p}{K}^{+}n$ final states from data samples of 14 million $\ensuremath{\psi}(2S)$ and 58 million $J/\ensuremath{\psi}$ events accumulated at the BES II detector. No $\ensuremath{\Theta}(1540)$ signal, the pentaquark candidate, is …
