Three Loop Top Quark Contributions to the rho Parameter
M. Faisst, J. Kuhn, T. Seidensticker +1
We present results for the three-loop top quark contributions to the rho parameter in the limit of large top quark mass. The simultaneous dependence on the mass of the Higgs boson…
Three-Loop Leading Top Mass Contributions to the rho Parameter
J. J. van der Bij, K. G. Chetyrkin, M. Faisst +2
We present analytical results for the leading contributions of the top quark to the electroweak rho parameter at order GF^3 Mt^6 and GF^2 Mt^4 alpha_s. The Higgs boson and the gaug…
Two Loop QCD Vertices and Three Loop MOM functions
K. G. Chetyrkin, T. Seidensticker
We present numerical results for the two loop QCD corrections to the ghost gluon vertex, the quark gluon vertex, and the triple gluon vertex in the massless limit at the symmetric…
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…
Second Order Corrections to the Muon Lifetime and the Semileptonic B Decay
M. Steinhauser, T. Seidensticker
In this article two-loop QED corrections to the muon decay and corrections of order to the semileptonic decay of the bottom quark are considered. We compute the imaginary p…
Second Order QCD Corrections to
K. G. Chetyrkin, R. Harlander, T. Seidensticker +1
Corrections of to the decay of the top quark into a W boson and a bottom quark are calculated. The method is based on an expansion of the top quark propagator for small…
