Abstract:
In this paper by using the generalized moment analysis[1] we have studied the structure of the wide resonance peak at about 1.7GeV produced in J/ψ radiative decay.It provides a method to test whether there exist the θf2(1720) and the G(1590) states simultaneously in the peak.If the G(1590) exists indeed it is a direct check for G(1590) as the 0++ glueball candidate.
