Abstract

The coherent reaction pd → pdπ⁺π^- is studied in pd collisions at 11.6 GeV/c. Strong Δ⁺⁺ (1236) production together with some dπ^- enhancement (d^0*) at ∼2200 MeV are found in this reaction. The mass spectrum of the pure I = 1 2 combination pπ⁺π^- shows a significant peak at ∼1460 MeV. A double Regge fit describes the general feature of the M(pπ⁺π^-) distribution, but does not reproduce the narrow peak. Comparison with a similar analysis at 7.0 GeV/c shows the same results, however the d^0* cross section decreases with incident energy.
