Sinha, R

I show that the existence of glueballs is necessary as a consequence of the meson mass spectrum, if, one assumes asymptotic freedom and unitarity. From similar arguments, with minimum dependence on specific models, I find limits on the masses of vector and tensor glueballs. I construct a nonorthogonal mixing model which works well for all but the scalar nonet. Within such a mixing model I find the iota unlikely to be a glueball. I expect glueballs to contribute little to the decay rates of mesons, however the meson masses do depend sensitively on glueballs. Also, I expect psi ..-->.. ..gamma..+ glueball decay rate to be small. In view of this, the resonances g/sub T/(2120), g/sub T/(2220) and g/sub T/(2360) can consistently be explained as glueballs.
