$B$ meson mixing at NNLO: technical aspects

High Energy Physics - Phenomenology 2024-05-24 v1

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 BB mesons. This includes the computation of the master integrals for finite charm and bottom quark masses, traces over products of up to 22 γ\gamma matrices and tensor integrals with up to rank 11.
