Charge- and hypercharge-exchange processes in the Veneziano model

Процессы с обменом эарядами и гиперэарядами в модели Венециано

Summary

We have studied various charge- and hypercharge-exchange processes in the Veneziano model. Differential cross-sections have been calculated for charge-exchange processes like ’πp →ηn, Kp →\(\bar K\) 0n and K+n → K0p, and hypercharge-exchange processes like Kn → πΛ and Kp → πΣ+. Polarization has been calculated for certain processes. We find fairly good fit for the differential cross-sections. Our results for polarization are in qualitative agreement with experimental results.

Riassunto

Si sono studiati vari processi con scambio di carica e di ipercarica nel modello di Veneziano. Si sono calcolate le sezioni d’urto per processi con scambio di carica come πp → ηn, Kp →\(\bar K\) 0n e K+n → K0p, e per processi con scambio di ipercarica come Kn → π Λ e K p → πΣ+. Per alcuni processi si è calcolata la polarizzazione. Si trova un accordo abbastanza buono per le sezioni d’urto differenziali. I nostri risultati per la polarizzazione concordano qualitativamente con i risultati sperimentali.

Реэюме

В модели Венециано мы исследовали раэличные процессы с обменом эарядами и гиперэарядами. Были вычислены дифференциальные поперечные сечения для процессов переэарядки, подобных πp → ηn, Kp → K0n и K+p → K0p, и процессов с обменом гиперэарядами, подобных Kn → πΛ и Kp → πΣ+. Для некоторых процессов была вычислена поляриэация. Мы получаем довольно хорощее соответствие для дифференциальных поперечных сечений. Нащи реэультаты для поляриэации качественно согласуются с зкспериментальными реэультатами.
