Abstract

Evidence is presented for an enhancement in the ωππ mass spectrum at the A2 mass region in π+p interactions at 5 GeV/c. Assuming this effect to be the A2, we calculate the decay rate relative to the ρπ decay mode and obtain the results 0.29 ± 0.08 and 0.10 ± 0.04 for the two final states A20Δ++ and A2+p, respectively. Possible explanations of the discrepancy between these numbers are suggested.
