摘      要：The property of σ-meson or f0(400-1200)is studied in the general color symmetry model(GCM)for quantum *** recent determined values of mσ,fσand fπin GCM,the isoscalarππS-wave amplitude is calculated without any free *** T-matrix pole for f0(400-1200)is found to be 1011-i 284MeV,which is very close to the Particle Data Group value(400-1200)-i(300-500)MeV.
