The Reggeon Field Theory and finite scales at collider energies

The Reggeon Field Theory (RFT) with attention paid to finite ''flavoring'' rapidity scales is considered in the light of emerging SPS collider data. Predictions from a simple RFT perturbative model made in 1978 are shown to be consistent with sigmasub(tot) and other data, in both the P-f identity and P+f versions. The RFT scaling laws are judged not applicable without large non-leading terms, implying an asymptotic regions beyond the collider. (orig.)
