A phenomenological dual description of the reactions K+p→K*0π+p and Kp→ K - *0πp

  • S. Papageorgiou
Article

Summary

The reactions K+p→K*0π+p and Kp→ K - *0πp are studied with a dual five-point amplitude. An appropriate kinematical factor suitable for six-particle systems is used. The pomeron-exchange contribution is excluded. With the help of the longitudinal phase-space analysis the kinematical domain of the model is defined and a suitable selection of the data is performed. An overall agreement (characteristic of the phenomenological dual-vector model) is obtained.

Феноменологическое дуальное описание реакций K+p → K*0π+p и Kp → K - *0π{s∪-}pp

Реэюме

С помошью дуальной пяти-частичной амплитуды исследуются реакции K+p → K*0π+p и Kp → K - *0πp. При аналиэе испольэуется кинематический фактор, соответствуюший для щести-частичных систем. Вклад от обмена Помероном исключается. С помошью аналиэа продольного фаэового пространства определяется кинематическая область модели и проводится соответствуюший отбор данных. Получается раэумное согласие (характерное для феноменологической дуальной векторной модели).

Riassunto

Si studiano le reazioni K+p→K*0π+p e Kp→ K - *0πp con un’ampiezza duale di cinque punti. Si adopera un fattore cinematico appropriato adatto per sistemi di sei particelle. Si esclude il contributo dello scambio del pomerone. Con l’aiuto dell’analisi dello spazio delle fasi longitudinali si definisce il dominio cinematico del modello e si effettua un’opportuna scelta dei dati. Si ottiene un accordo generale (caratteristico del modello fenomenologico del vettore duale).
