Two-loop QED hadronic corrections to Bhabha scattering
Johann H. Kühn, Sandro Uccirati
Theoretical predictions for Bhabha scattering at the two-loop level require the inclusion of hadronic vacuum polarization in the photon propagator. We present predictions for the c…
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…
Four-pion production in tau decays and e+e- annihilation: an update
Henryk Czyz, Johann H. Kuhn, Agnieszka Wapienik
An improved description of four-pion production in electron-positron annihilation and in tau lepton decays is presented. The model amplitude is fitted to recent data from BaBar whi…
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…
