Abstract We consider reactions of the type ab→cdR in the double-Regge region. The cross sections are proportional to the reggeon-reggeon forward amplitude in the resonance region. Using semi-local duality the cross sections can be written in terms of the relevant triple-Regge couplings which are already known from reggeon-particle scattering, i.e. from analysing data on reactions of the type ab→cR. We compare the predictions of pp→pp ( ϱ, f) π −p→ π −p ( ϱ, f) with data at 12, 24 and 205 GeV/ c and find encouraging results. We suggest a series of cross sections, the measurement of which will provide a definite test of the duality hypothesis for reggeon-reggeon scattering.
