十重态到八重态重子和赝标介子的强跃迁

Strong transitions of decuplet to octet baryons and pseudoscalar mesons

T. M. Aliev, K. Azizi, M. Savci

摘要:

在考虑$SU(3)_f$对称性破缺效应的光锥QCD求和规则下,研究了轻赝标$π$、$K$和$η$介子与十重态-八重态重子的强耦合常数.结果表明,即使将$SU(3)_f$对称性破缺效应引入博弈中,所考虑的所有耦合常数也仅由一个普适函数描述。

英文摘要:

The strong coupling constants of light pseudoscalar $π$, $K$ and $η$ mesons with decuplet--octet baryons are studied within light cone QCD sum rules, where $SU(3)_f$ symmetry breaking effects are taken into account. It is obtained that all coupling constants under the consideration are described by only one universal function even if $SU(3)_f$ symmetry breaking effects are switched into the game.
