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 ΔΓs in the Bs - (Equation presented)s system. We focus on the treatment of spinor structures with products of up to 22 γ matrices by means of projection and tensor integrals. Moreover, we present an approach for the semi-numeric computation of master integrals.
