We have studied inclusive ..delta../sup + +/ production at 147 GeV/c in pp, K/sup +/p, ..pi../sup +/p, and ..pi../sup -/p interactions. All four reactions were detected with the same apparatus and analyzed in the same way. The energy dependence of the ..delta../sup + +/ cross section was found to be Ap/sup -1/+B for pp, K/sup +/p, and ..pi../sup +/p interactions and constant for ..pi../sup -/p interactions. The shape of the inclusive ..delta../sup + +/ distributions does not depend on the beam, while the magnitudes are proportional to the total cross sections. We have obtained the effective trajectory at the p-..delta../sup + +/ vertex from a triple-Regge analysis and found that all results are consistent with predictions of a triple-Regge diagram where a Pomeron is exchanged at the beam vertex and a ..pi.. at the target vertex.
