用QCD求和规则破译三重重子

Deciphering triply heavy baryons in terms of QCD sum rules

Jian-Rong Zhang, Ming-Qiu Huang

摘要:

用QCD求和规则系统地解释和计算了基态三重重子的质量谱。利用$QQQ'$的一个试探性的$(QQ)-(Q')$组态,提出了代表三重重子的内插流.从技术上讲,直到第六维的算子的贡献都包括在算子乘积展开(OPE)中。与其他理论预测的数值结果进行了比较。

英文摘要:

The mass spectra of ground-state triply heavy baryons are systematically unscrambled and computed in QCD sum rules. With a tentative $(QQ)-(Q')$ configuration for $QQQ'$, the interpolating currents representing the triply heavy baryons are proposed. Technically, contributions of the operators up to dimension six are included in operator product expansion (OPE). The numerical results are presented in comparison with other theoretical predictions.
