By postulating naive tensor-meson dominance in the energy-momentum-tensor couplings, we find that, in addition to f and f, another tensor meson is needed to explain the ratio of (fKK)/(f). Considering (1720), the tensor-glueball candidate, as this meson we obtain the matrix element 0. The branching ratio of (1720) in J/ radiative decay is thus calculated which agrees very well with the observed experimental branching ratio of (1720) which decays to KK, , and .
