Absorptive cuts in forward high-energy collisions

Absorptive corrections to ordinary Reggeon exchange in different hadron-nucleon forward amplitudes are evaluated assuming they are due to diffractive-rescattering effects. No hypothesis concerning the t structure of amplitudes is required and only rho universality at t = 0 has been assumed. Using independent sets of data, cut corrections are consistently found to be destructive and rather large, representing typically 30% of the pole contribution to meson-nucleon amplitudes.
