説明
The data on the π^-p → M^0n, with M^0 = π^0π^0π^0 orπ^0π^0η obtained in the GAMS experiment may be useful to study the σ(400 〜 700) and a^χ_1(〜1000), which can be taken as chiral partners of π and ρ, respectively. A preliminary analysis for 3π^0 invariant mass spectra gives a support for the assumed a^χ_1 with a mass of 〜 930MeV and Γ 〜 170MeV.
