$\{Q\bar{q}\}\{\bar{Q}^{(')}q\}$分子状态

$\{Q\bar{q}\}\{\bar{Q}^{(')}q\}$ molecular states

Jian-Rong Zhang, Ming-Qiu Huang

摘要:

在QCD求和规则下,系统地研究了$\{Q\bar{q}\}\{\bar{Q}^{(')}q\}$分子态的质量。提出了代表相关分子态的插值电流。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。得到了具有$\{Q\bar{q}\}\{\bar{Q}^{(')}q\}$构型的分子态的质谱。

英文摘要:

Masses for $\{Q\bar{q}\}\{\bar{Q}^{(')}q\}$ molecular states are systematically studied in QCD sum rules. The interpolating currents representing the related molecular states are proposed. Technically, contributions of the operators up to dimension six are included in operator product expansion (OPE). Mass spectra for molecular states with $\{Q\bar{q}\}\{\bar{Q}^{(')}q\}$ configurations are obtained.
