QCD中的重子谱

Heavy baryon spectroscopy in QCD

Jian-Rong Zhang, Ming-Qiu Huang

摘要:

我们在QCD求和规则的框架下对粲重子和底重子的质量进行了系统的研究。直到维度6的算子的贡献被包括在算子乘积展开中。计算得到的重子质量与实验值符合得很好,并对未观测到的底重子的光谱进行了预测。

英文摘要:

We perform a systematic study of the masses of charmed and bottom baryons in the framework of the QCD sum rule approach. Contributions of the operators up to dimension six are included in operator product expansion. The resulting heavy baryon masses from the calculations are well consistent with the experimental values, and predictions to the spectroscopy of the unobserved bottom baryons are also presented.
