Identification of [f2(1720)] as a tensor glueball

By incorporating a soft form factor, we show that [f2(1720)] has flavor-independent decays to KK»and ee. The same form factor is needed to understand the suppression of in K-pKS0KS0 as well as its emergence in the central productions of epe(K+K-)p and ppp(K+K-)p. This flavor-symmetric feature of is further enhanced by comparing f2e(1525) and in J decays to KK» KK» and KK» The absence of in KS0KS0 and K-pKS0KS0 leads us to conclude that the quark content in is very low. With shown to be a flavor singlet and void of quarks, we believe that could indeed be a tensor glueball, subject to the verification of the soft form factor.
