轻矢量介子与重子强相互作用

Light vector meson and heavy baryon strong interaction

Peng-Zhi Huang, Hua-Xing Chen, Shi-Lin Zhu

摘要:

在重夸克有效理论的首阶轻锥QCD求和规则的框架下,计算了轻矢量介子与重子之间的耦合常数。大多数求和规则随Borel参数和连续阈值的变化是稳定的。所提取的耦合对研究可能的重子分子态是有用的。

英文摘要:

We calculate the coupling constants between the light vector mesons and heavy baryons within the framework of the light-cone QCD sum rule in the leading order of heavy quark effective theory. Most resulting sum rules are stable with the variations of the Borel parameter and the continuum threshold. The extracted couplings will be useful in the study of the possible heavy baryon molecular states.
