We emphasise the sizeable effects of absorption on high-energy ‘soft’ processes, and, hence, the necessity to include multi-pomeron–pomeron interactions in the usual multi-channel eikonal description. We present a model which includes a complete set of the multi-pomeron vertices and which accounts for the diffusion in both the impact parameter and ln (k t ) of the parton during its evolution in rapidity. We tune the model to the available data for soft processes in the CERN-ISR to the Tevatron energy range. We make predictions for ‘soft’ observables at the LHC.
