Constraints of duality on Regge couplings

Ограничения дуальности на свяэи Редже

Summary

The application of duality in the form of finite-mass sum rules (FMSR) makes it possible, under certain conditions, to express the Regge couplings which appear in quasi-two-body reactions in terms of the triple-Regge vertex. The method is applied to ρ-π scattering, where ρ is a reggeon and π a particle, and, using for the triple-Regge coupling the values obtained in a dual unitary calculation, we get results in fair agreement with experiment.

Riassunto

L’applicazione della dualità nella forma delle regole di somma della massa finita (RSMF) rende possibile, in certe condizioni, esprimere gli accoppiamenti di Regge che appaiono nelle reazioni di quasi due corpi in termini del vertice di Regge triplo. Si applica il metodo allo scattering ρ-π dove ρ è un reggeone e π una particella, e usando per l’accoppiamento di Regge triplo i valori ottenuti in un calcolo unitario duale, si ottengono risultati in buon accordo con gli esperimenti.

Реэюме

При определенных условиях применение дуальности в виде правил сумм с конечной массой поэволяет выраэить свяэи Редже, которые появляются в кваэи-двухчастичных реакциях, череэ тройную верщину Редже. Предложенный метод применяется к ρ-π рассеянию, где ρ есть реджеон и π представляет частицу. Испольэуя для тройной свяэи Редже эначения, полученные при дуальном унитарном вычислении, мы получаем реэультаты, хорощо согласуюшиеся с зкспериментом.
