重自旋3/2重子与轻赝标介子的强耦合常数

Strong coupling constants of heavy spin--3/2 baryons with light pseudoscalar mesons

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

摘要:

在轻锥QCD求和规则框架下,计算了含单重夸克的重自旋-3/2重子与轻赝标介子的强耦合常数。利用对称性论证,得到了不同关联函数之间的结构无关关系。结果表明,所有可能的过渡可以描述在一个通用的不变函数,其显式表达式是洛伦兹结构依赖。

英文摘要:

The strong coupling constants among members of the heavy spin--3/2 baryons containing single heavy quark with light pseudoscalar mesons are calculated in the framework of the light cone QCD sum rules. Using symmetry arguments, the structure independent relations among different correlation functions are obtained. It is shown that all possible transitions can be described in terms of one universal invariant function whose explicit expression is Lorenz structure dependent.
