【 摘 要 】

I briefly specify elements of the GLM model that successfully describes soft hadronic interactions at energies from ISR to LHC. The model is based on a single Pomeron with a large intercept ΔIP= 0.23 and slope α'IP= 0.028, and so provides a natural matching with perturbative QCD. I analyze the elastic, single diffractive and double diffractive amplitudes, and compare the behaviour of the GLM amplitudes to those of other parameterizations. I then summarize the main features and results of the GLM model and compare with those of the Kaidalov-Poghosyan and other models for soft interactions at high energies.
