New Results in Four and Five Loop QED calculations
P. A. Baikov, K. G. Chetyrkin, C. Sturm
We report on two recent multiloop results in QED: (i) the four-loop corrections to the conversion relations between the QED charge renormalized in the on-shell and MS-bar schemes;…
High-Precision Charm-Quark Mass and QCD Coupling from Current-Current Correlators in Lattice and Continuum QCD
I. Allison, E. Dalgic, C. T. H. Davies +12
We use lattice QCD simulations, with MILC gluon configurations and HISQ c-quark propagators, to make very precise determinations of moments of charm-quark pseudoscalar, vector and…
Hadronic Z- and tau-Decays in Order alpha_s^4
P. A. Baikov, K. G. Chetyrkin, J. H. Kühn
Using recently developed methods for the evaluation of five-loop amplitudes in perturbative QCD, corrections of order alpha_s^4 for the cross section of electron-positron annihilat…
Towards NNLO Accuracy in the QCD Sum Rule for the Kaon Distribution Amplitude
K. G. Chetyrkin, A. Khodjamirian, A. A. Pivovarov
We calculate the and gluon radiative corrections to the QCD sum rule for the first Gegenbauer moment of the kaon light-cone distribution amplitude. The…
