Reconstruction of heavy quark current correlators at O(α_s^3)

Y. Kiyo, A. Maier, P. Maierhoefer +1

We construct approximate formulas for the O(α_s^3) QCD contributions to vector, axial-vector, scalar and pseudo-scalar quark current correlators, which are valid for arbitrary valu…

Low energy moments of heavy quark current correlators at four loops

A. Maier, P. Maierhoefer, P. Marquard +1

We describe several techniques for the calculation of multi-loop integrals and their application to heavy quark current correlators. As new results, we present the four-loop correc…

Higher Moments of Heavy Quark Correlators in the Low Energy Limit at O(alpha_s^2)

A. Maier, P. Maierhoefer, P. Marquard

We present the first 30 moments of the low energy expansions of the vector, axial-vector, scalar and pseudo-scalar heavy quark correlation functions at three-loop order, including…

Standard and epsilon-finite Master Integrals for the rho-Parameter

M. Faisst, P. Maierhoefer, C. Sturm

We have constructed an epsilon-finite basis of master integrals for all new types of one-scale tadpoles which appear in the calculation of the four-loop QCD corrections to the elec…

Four-Loop QCD Corrections to the Rho Parameter

K. G. Chetyrkin, M. Faisst, J. H. Kühn +2

The four-loop QCD corrections to the electroweak -parameter arising from top and bottom quark loops are computed. Specifically we evaluate the missing ``non-singlet'' piece. Usi…
