The diffractively produced low-mass π+π−p system isstudied in the reaction π±p → π±π+π−p. We observe strong N∗(1700) production and determine the branching fraction to π−Δ++ to be 65 ± 15%. A spin-parity analysis (assuming J 7 2 ) yields J P = 5 2 + for the N∗(1700). The study of the decay angular distribution of the N∗(1700) indicates that helicity is conserved in the t-channel rather than in the s-channel. |
