摘要：
The property of sigma-meson or f0(400-1200) is studied in the general color symmetry model (GCM) for quantum chromodynamics. With recent determined values of m(sigma), f(sigma) and f(pi) in GCM, the isoscalar pi pi S-wave amplitude is calculated without any free parameter. The T-matrix pole for f0(400-1200) is found to be 1011-i 284 MeV, which is very close to the Particle Data Group value (400-1200)-i (300-500) MeV.
