AbstractThe radiative decay of J/psi into a pure gauge tensor glueball is studied in the quenched lattice QCD formalism. With two anisotropic lattices, the multipole amplitudes E-1(0), M-2(0), and E-3(0) are obtained to be 0.114(12)(6) GeV, -0.011(5)(1) GeV, and 0.023(8)(1) GeV, respectively. The first error comes from the statistics, the Q(2) interpolation, and the continuum extrapolation, while the second is due to the uncertainty of the scale parameter r(0)(-1) = 410(20) MeV. Thus, the partial decay width Gamma(J/psi -> gamma G(2++)) is estimated to be 1.01(22)(10) keV, which corresponds to a large branch ratio 1.1(2)(1) x 10(-2). The phenomenological implication of this result is also discussed.
