d WAVE COMPONENTS OF THE GLUEBALL CANDIDATE θ/f2(1720) AND POSSIBLE EXPERIMENTAL TEST

  •  Institute of High Energy Physics,Academia Sinica,Beijing

  • In this paper we discuss the production and decay of the glueball candidate θ/f2(1720) in the J/ψ radiative decay.We find that in order to explain the helicity amplitude ratios x and y of the process J/ψ→γ+θ,the contribution of two D wave components (l=2,S=0,2) has to be considered in addition to the S wave component.We also discuss the possible experimental test for the existence of the D′wave component (l=2,S=2).

Abstract: In this paper we discuss the production and decay of the glueball candidate θ/f2(1720) in the J/ψ radiative decay.We find that in order to explain the helicity amplitude ratios x and y of the process J/ψ→γ+θ,the contribution of two D wave components (l=2,S=0,2) has to be considered in addition to the S wave component.We also discuss the possible experimental test for the existence of the D′wave component (l=2,S=2).
