The analysis of decay channels JΨ → γγV(ϱ,f) Original Research Article

Based on 7.8 × 106, View the MathML source events collected by the BES experiment, View the MathML source radiative decay channels View the MathML source have been studied. The η(1430) resonance has been observed in these two channels respectively. Its mass and width are 1431 ± 17 MeV and 88 ± 28 MeV from the View the MathML source mode, 1427 ± 13 MeV and 77 ± 46 MeV from the View the MathML source mode.
