Measurement of the Pi^- p -> 3 Pi^0 N Total Cross-Section From Threshold to 0.75 GeV/c
We report a new measurement of the pi(-)p-->3pi(0)n total cross section from threshold to p(pi)=0.75 GeV/c. The cross section near the N(1535)1/2(-) resonance is only a few mub after subtracting the large eta-->3pi(0) background associated with pi(-)p-->etan. A simple analysis of our data results in the estimated branching fraction B[S-11-->piN(1440)1/2(+)]=(8+/-2)%. This is the first such estimate obtained with a three-pion production reaction.
