论文摘要

我们计算参考文献的三环主积分。 [1] [Arxiv:1709.02160]分析形式。这使我们能够向$ b $ - $ \ $ \ bar b $ decay矩阵的$ΔB= 2 $ wilson系数提出fermionic贡献,并在QCD的近临界顺序中,完全分析了Fermionic循环中Charm Quark的质量。

We calculate the three-loop master integrals of Ref. [1] [arXiv:1709.02160] in analytic form. This allows us to present the fermionic contributions to the $ΔB=2$ Wilson coefficients of the $B$-$\bar B$ decay matrix in next-to-next-to-leading order of QCD with full analytic dependence on the mass of the charm quark in the fermionic loops.
