论文摘要

作为[Phys.Rev.D 102(2020),034034]的连续作品,我们将$ 1/m_q $校正得出了授权的lagrangian,以适用于QCD的重型梅森,在适当的近似值下。有效的拉格朗日语中低能常数以光夸克自我能源和重夸克质量$ m_q $表示。给出了$ 1/m_q $校正的低能常数的数值结果。我们发现,与在重夸克极限中获得的结果相比,斜腐衰变常数和重型介子的质量相比得到了一致的改进。

As a successive work to [Phys.Rev.D 102 (2020), 034034], we derive the $1/m_Q$ corrections to chiral effective Lagrangian for heavy-light mesons from QCD under proper approximations. The low energy constants in the effective Lagrangian are expressed in terms of the light quark self-energy and heavy quark mass $m_Q$. Numerical results of the low energy constants with $1/m_Q$ corrections are given. We find that the results of pion decay constant and the masses of heavy-light mesons are improved coherently compared to that obtained in the heavy quark limit.
