Analysis of the bottom-charm baryon states with QCD sum rules

Abstract

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 $\mu =2.0\sim 2.8\mathrm{GeV}$, while the best energy scale is $\mu =2.0\mathrm{GeV}$. The predictions can be confronted to the experimental data in the future and shed light on the QCD low energy dynamics.
