SCALAR GLUEBALL - ANALYSIS OF THE (IJ(PC)=00(-WAVE(+)))

Rasing on the previously pet-formed K-matrix analysis of experimental data, we investigate, in the framework of the propagator matrix (D-mat rix) technique, the 1100-1900 MeV mass region, where overlapping reson ances f(0)(1300), f(0)(1500), f(0) (1530 +/- 90/250), and f(0)(1780) a re located. Necessary elements of the D-matrix technique are developed . The D-matrix analysis confirms previous K-matrix results: in the reg ion 900-1900 MeV five scalar/isoscalar states are located. Four of the m are members of the two <q(q)over bar>-nonets, while one state is an extra for the <q(q)over bar> systematics, being a good candidate for t he lightest scalar glueball. The D-matrix analysis shows that this ext ra state, a candidate for the lightest scalar glueball, is dispersed, due to a mixing with <q(q)over bar>-states, over three resonances: f(0 )(1300), f(0)(1500), and f(0)(1530+/-90/250). The broad resonance f(0) (1530+/-90/250) is a descendant of the lightest glueball, carrying ab out 50% of the gluonium component, the rest of the gluonium is shared between f(0)(1300) and f(0)(1500). The broad resonance is formed by ac cumulating a large part of the neighbouring resonance widths that elab orates some type of a trap for the adjoining states.
