The $\msbar$ Renormalized Bottom Mass of Order and its Application to
Axel Kwiatkowski, Matthias Steinhauser
The renormalized mass of the bottom quark is calculated at the two loop level to order in the $\msbar$ renormalization scheme. Different strategies for th…
Three-Loop O(alpha_s^2 G_F M_t^2) Corrections to Higgs Production and Decay at e^+e^- Colliders
B. A. Kniehl, M. Steinhauser
We evaluate the next-to-leading-order QCD corrections of O(alpha_s^2 G_F M_t^2) to the Standard-Model l^+l^-H, ZZH, and W^+W^-H couplings in the heavy-top- quark limit. Exploiting…
Virtual Top Effects on Low-Mass Higgs Interactions at Next-to-Leading Order in QCD
B. A. Kniehl, M. Steinhauser
We present the next-to-leading-order QCD corrections of O(alpha_s^2 G_F M_t^2) to the low-M_H effective l^+l^-H, ZZH, and W^+W^-H interaction Lagrangians in the high-M_t limit. In…
Corrections of order ${\cal O}(G_F M_t^2 \as^2)$ to the parameter
K. G. Chetyrkin, J. H. Kuehn, M. Steinhauser
The three-loop QCD corrections to the parameter from top and bottom quark loops are calculated. The result differs from the one recently calculated by Avdeev et al. As function…
