论文摘要

在这项工作中,我们以全面的方式探索了QCD总规则框架中底部链式巴里昂州的基质量谱。在计算中,我们明确地区分了积极差异和负态巴属状态的贡献,并在详细信息中调查了QCD总规则的能量尺度依赖性,并观察到可接受的能量尺度为$ = 2.0 \ sim 2.8 \,\ rm {gev} $,而最佳能量量表是$ = 2.0 \ cev gev。将来可以将预测与实验数据面对面,并阐明QCD低能动力学。

In this work, we explore the ground state mass spectrum of the bottom-charm baryon states in the framework of the QCD sum rules in a comprehensive way. In calculations, we distinguish the contributions of the positive-parity and negative-parity baryon states unambiguously, and investigate the energy scale dependence of the QCD sum rules in details and observe that the acceptable energy scales are $μ=2.0\sim 2.8\,\rm{GeV}$, while the best energy scale is $μ=2.0\,\rm{GeV}$. The predictions can be confronted to the experimental data in the future and shed light on the QCD low energy dynamics.
