Abstract

Within a very crude approach, we show that the multiparticle unitarity constraint can be invoked to account for the origin of the leading-particle effect in high-energy hadronic processes. The quasielastic peak of inclusivep⊥ distributions and the diffractive behaviour around |x| ≃ 1 (x being the Feynman normalized momentum) emerge naturally. The limitations of the approach are briefly discussed. Nell’ambito di un modello molto rozzo, si mogtra che la condizione di unitarieta a molte particelle puo essore considerata responsabile dell’origine dell’efletto di particella guida in processi adroniei di alta energia. II picco quasi elastico inp⊥ delle distribuzioni inclusive e il comportamento diffrattivo vicino a |x| ≃1 (x essendo la variabile di Feynman) emergono in maniera naturale. I limiti del modello sono brevemente discussi.
