dc.description.abstractBased on (10087±44)×10^{6}??J/? events collected with the BESIII detector, the process J/????^{+}?^{-}?^{'} is studied using two largest decay channels of the ?^{'} meson, ?^{'}???^{+}?^{-} and ?^{'}???^{+}?^{-}, ????. A new resonance, which we denote as the X(2600), is observed with a statistical significance larger than 20? in the ?^{+}?^{-}?^{'} invariant mass spectrum, and it has a connection to a structure around 1.5??GeV/c^{2} in the ?^{+}?^{-} invariant mass spectrum. A simultaneous fit on the ?^{+}?^{-}?^{'} and ?^{+}?^{-} invariant mass spectra with the two ?^{'} decay modes indicates that the mass and width of the X(2600) state are 2618.3±2.0_{-1.4}^{+16.3}??MeV/c^{2} and 195±5_{-17}^{+26}??MeV, where the first uncertainties are statistical, and the second systematic.en_US
