Abstract
The technique of the propagator matrix is developed for analyzing the IJ(PC)=00(++) wave. On the basis of the K-matrix analysis of experimen tal data that was performed previously, the mass region 1200-1600 MeV, which contains the overlapping scalar resonances f(0)(1300), f(0)(150 0), and f(0)(1530+/-(90)(250)), is studied within this technique. It i s shown that, owing to mixing, the state that can be considered as a c andidate for the lowest scalar glueball is dispersed over the above th ree resonances.
