Addendum: Towards next-to-next-to-leading-log accuracy for the width difference in the $\mathbf{B_s-\bar{B}_s}$ system: fermionic contributions to order $\mathbf{(m_c/m_b)^0}$ and $\mathbf{(m_c/m_b)^1}$

preprint2022arXivOpen access

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.
