Abstract
This report summarises important technical challenges and their solutions in the calculation of the next-to-next-to-leading order QCD corrections to the width difference in the system. We focus on the treatment of spinor structures with products of up to 22 matrices by means of projection and tensor integrals. Moreover, we present an approach for the semi-numeric computation of master integrals.
