Second Order QCD Corrections to the Top Decay Rate

K. G. Chetyrkin, R. Harlander, T. Seidensticker +1

We report on a recent calculation of the top decay rate up to order α_s^2. It is based on asymptotic expansions of the off-shell top propagator, followed by a Padé approximation in…

Hadronic contribution to $α (M_{Z}^{2})$ and the anomalous magnetic moment of the muon

M. Steinhauser

In this contribution recent developments are discussed which lead to a significant reduction of the error for $α (M_{Z}^{2})$ and $(g - 2)_{μ}$ .
