Coupling constants for 2+ and 1 meson nonets and the 0 meson octet in a model with infinite multiplets

  • W. Rühl


We investigate the possibility of assigning 2+ and 1 meson resonances to states of one intinite unitary representation of the groupSL2,c. We compute vertex functions for the decays of these resonances into two pseudoscalar mesons or one pseudoscalar and one axial vector meson.

Константы связи для 2+ и 1 мезонных нонетов и 0 мезонного октета в модели с бесконечными мультиплетами


Мы исследуем возможность приписывания 2+, и 1 мезонных резонансов состояниям одного бесконечного унитарного представления группыSL2,c. Мы вычисляем вершинные функции для распадов этих резонансов в два псевдоскалярных мезона или один псевдоскалярный, а другой аксиальный векторный мезон.


Si esamina la possibilità di assegnare le risonanze mesoniche 2+ e 1 agli stati di una rappresentazione unitaria infinita del gruppoSL2,c. Si calcolano le funzioni di vertice per il decadimento di queste risonanze in due mesoni pseudoscalari o un mesone pseudoscalare e uno vettoriale assiale.
