Double Regge Exchange in rho delta pi and rho rho N Final States from pi exp - p Interactions at 8 GeV/C

摘要

We present a comparison of the double Regge model with the results from rho delta pi , rho rho N and nA sub 2- pi exp + production from pi exp - p interactions. Our study differs from previous studies in that a Deck type mechanism is forbidden by internal quantum number conservation at the vertices, and, thus, represents a more general test of the double-Regge model in the 5 to 20 GeV energy range. The large statistics of our exposure enabled an adequate sample of the desired final states to conduct such a comparison. The gross features of the data, when restricted to definite peripheral regions of phase space, were accounted for by a combination of simple Regge exchanges. The details of the model do require a more elaborate analysis. (ERA citation 08:013257)
