Abstract

We provide details to several technical aspects which are important for the calculation of next-to-next-to-leading order corrections to the mixing of neutral B mesons. This includes the computation of the master integrals for finite charm and bottom quark masses, traces over products of up to 22 γ matrices and tensor integrals with up to rank 11.
