摘要：
Preliminary results of spin-parity analysis of the antiproton-proton annihilation into the pi (+)pi (-)pi (+)pi (-)pi (0) final state at the (p) over bar momentum 50MeV/c are reported. The fit was found to depend considerably on the parameters of the pi (+)pi (-) S-wave state - f(0)(400-1200) or sigma meson, requiring the low value for the mass of sigma. The best result is obtained with the sigma mass M-sigma = (392 +/- 6)MeV and width Gamma (sigma) = (528 +/- 20)MeV.
