Abstract:
In this paper, the structure of the wide resonance peak produced in the J/ψ radioactive decay around 1.7 GeV is studied in terms of the generalized moment analysis[1], and a method of testing whether there simultaneously exist the Θ/f2(1720) and G(1590) states in the peak is provided. The result shows that G(1590) really exists, and it will be a direct evidence that the G(1590) is a candidate of the 0++ glueball.
