Abstract

We report a new measurement of the π^-p→3π ⁰ total cross section from threshold to p_π=0.75 GeV/c. The cross section near the N (1535)1/2π^- resonance is only a few μb after subtracting the large η3π₀ background associated with ππ^-p→n. A simple analysis of our data results in the estimated branching fraction B[S₁₁→πN(1440)1/2⁺ = (8±2)%. This is the first such estimate obtained with a three-pion production reaction.
