概要
- 論文の詳細を見る
Reactions which take place through the exchange of exotic quantum numbers, are investigated by taking account of the urbaryon rearrangement diagrams behind them and are classified into two classes. It is pointed out that these two classes are subject to different dynamical mechanism. The processes belonging to the first class are understood by the exotic meson exchange mechanism. The process pp^^-→YY^^- is analysed by introducing the exotic mesons based on the urbaryon rearrangement diagrams, and their dynamical properties are investigated. It is found that the exotic mesons strongly couple to nucleon-antihyperon (g_E sime 1.2g) and lie on low-lying trajectories with the intercept α_E(0)sime-1.25, whose slope (α^´_E sime 0.45) is flatter than the one of ordinary meson trajectories.
