Nuclear effects in the analysis of the ρ-ω mixing from photoproduction

Ядерные зффекты при аналиэе ρ-ω смещивания при фоторождении

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The coherent photoproduction of the ρ-meson from complex nuclei is analysed. By using an optical-model description of the process, the electromagnetic and nuclear ρ-ω mixing is considered in detail. A mixing parameter, describing the ratio (ω → π+π)/(ρ → π+π) for the amplitudes is derived in which the nuclear mixing parts are clearly exhibited.

Riassunto

Si analizza la fotoproduzione coerente di mesoni ρ da nuclei complessi. Si considera dettagliatamente, usando una descrizione del processo basata su un modello ottico, la misccla ϱ-ω elettromagnetica e nucleare. Si deriva il parametro di miscela, che deserive il rapporto (ω → π+π)/(ρ → π+π) per le ampiezze, in cui le parti della miscela nucleare sono chiaramente presentate.

Реэюме

Аналиэируется когерентное фоторождение ρ-меэона на сложных ядрах. Испольэуя оптическую модель для описания процесса, подробно рассматривается злектромагнитное и ядерное ρ-ω смеивание. Выводится параметр смещивания, описываюший отнощение (ω→π+π)/(ρ→π+π) для амплитуд, в который явно входят части ядерного смещивания.
