A critical pomeron's view of the total and triple-Regge inclusive cross sections

An investigation of the total and triple-Regge inclusive cross sections is carried out using a critical pomeron in the framework of reggeon field theory with thresholds. For a model with P and the conventional P' and ω poles, the rise of the total cross section cannot be accounted for. However, in a model with a single dual-unitarization-type vacuum singularity and the ω pole, the data can be adequately described. (Auth.)
