- Аннотация: The model-dependence of the relation be- tween the inelastic and various minimum-bias proton-proton cross sections is analyzed, pay- ing a special attention to the sensitivity of minimum-bias triggers to diffractive collisions. Concentrating on the trigger selections of the ATLAS experiment, the measured cross sections are compared to predictions of a number of hadronic Monte Carlo models used in the cosmic ray field. It is demonstrated that the ATLAS results are able to discriminate between differ- ent models and between certain theoretical ap- proaches for soft multi-particle production. On the other hand, the strong model-dependence of the selection efficiency of the minimum-bias triggers prevents one from inferring high mass diffraction rate from the discussed data. More- over, the measured cross sections prove to be in- sensitive to the production of low mass diffrac- tive states in proton-proton collisions. Conse- quently, a reliable determination of the total inelastic cross section requires forward proton tracking by a dedicated experiment.
