Summary

By applying a lepton-hadron relation, average multiplicities of charged (π, K) mesons and baryons-antibaryons in pp scattering have been found out which are in excellent agreement with experimental results. The proposed linkage between the rising total pp cross-section phenomenon and the antibaryon production has also been investigated and the result is found to be negative. The explanation of this rising pp cross-section phenomenon, in this model, is however attributed to the diffraction effects in which the black-core radius expands logarithmically with energy (RR0 lns) as suggested by Cheng, Walker and Wu.

Свяэь лептонов и адронов, средние множественности раэличных эаряженных вторичных частиц в pp рассеянии и некоторые эамечания о воэрастании pp полных поперечных сечений при ISR знергиях

Реэюме

Испольэуя свяэь лептонов и адронов, получаются средние множественности эаряженных (π, K) меэонов и барионов-антибарион ов в процессах рр рассеяния, которые хорощо согласуются с зкспериментальными реэультатами. Исследуется предложенная свяэь между явлениями воэрастания полного рр поперечного сечения и рождением антибарионов и получается отрицательный реэультат. В зтой модели явление воэрастания рр поперечного сечения приписывается дифракционным зффектам, когда радиус черного остова увеличивается логарифмически с знергией (RRo 1ns), как было предположено Ченгом, Уолкером и Ву.

Riassunto

Applicando una relazione leptone-adrone, si è trovato che molteplicità medie dei mesoni carichi (π, K) e dei barioni-antibarioni nello scattering pp sono in eccellente accordo con i risultati sperimentali. Si è anche analizzato il legame proposto tra il fenomeno di crescente sezione d’urto totale pp e la produzione di antibarioni e si è trovato un risultato negativo. La spiegazione di questo fenomeno di crescente sezione d’urto totale pp, in questo modello, è comunque attribuita agli effetti di diffrazione in cui il raggio del nucleo nero si sviluppa logaritmicamente con l’energia (RR0 lns) come suggerito da Cheng, Walker e Wu.
