Role of new exchanges in the reactions. pi. /sup +/p. -->. (rho/sup 0/,. omega. ). delta. /sup + +/(1238)
Since new exchanges were recently found to be important in the reactions ..pi../sup -/p..-->.. (rho/sup 0/,..omega..) n, a study is made of the role of these exchanges in the reactions ..pi../sup +/p..-->.. (rho/sup 0/,..omega..) ..delta../sup + +/. The new exchanges are interpreted as Regge cuts without the introduction of new trajectories. The ..pi../sup +/p..-->.. (rho/sup 0/,..omega..) ..delta../sup + +/ data for q/sub L/=7.1 GeV/c are fitted; the A/sub 2/A/sub 2/, rhorho, rhoA/sub 2/, and A/sub 2/rho cuts are taken into account in the process. Predictions are made regarding polarization effects of rho/sup 0/ and ..omega.. production and also for rho/sup 0/--..omega.. interference. These predictions can be tested experimentally.
