Abstract
The (IJ PC = 00++)-wave is analysed, and the qq̅-nonet classification of the observed states is settled. The analysis shows an existence of the scalar glueball state in the mass region 1300–1600 MeV. The pure glueball state is dispersed over three real resonances: f 0(1300), f 0(1500), and f 0(1530 ± 90250 ). Glueball/qq̅content of these resonances is restored.
