Abstract

The process p + nucleon → V⁰+ anything has been studied at 300 GeV for V⁰ = Λ⁰, Λ⁰, and K_S⁰. The data are consistent with a simple Mueller-Regge formulation in the appropriate limit. Values of α(t) computed from the data agree with those expected from the simplest triple-Regge diagrams. If the pomeron is not a pure SU(3) singlet, a similar diagram is consistent with the Feynman x-dependence of the observed polarization of inclusively produced Λ⁰.
