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…
The second physical moment of the heavy quark vector correlator at O(alpha_s^3)
A. Maier, P. Maierhoefer, P. Marquard
The second moment of the heavy quark vector correlator at O(alpha_s^3) is presented. The implications of this result on recent determinations of the charm and bottom quark mass are…
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…
