Title Evidence for a a scalar glueball
Abstract We show that the newly discovered scalar meson fo(1500) at LEAR has properties compatible with the lightest scalar glueball predicted by lattice QCD and incompatible with a QQ state. We suggest that decays of glueballs are into pairs of glue balls (including 11, 11' or ( 7r7r )s) or by mixing with nearby QQ states. The partial widths of fo(1500) are in accord with this hypothesis, tests of which include characteristic radiative decays to "(l/1, "(W, 'YP and the prediction of a further scalar state, !0(1500- 1800) which couples strongly to KK, 1111 and 1111'ยท
