Extracting alpha_s from Electron-Positron Annihilation around 10 GeV

K. G. Chetyrkin, J. H. Kuhn, T. Teubner

The total cross section for electron-positron annihilation into hadrons is calculated in the region just below the B meson threshold. QCD corrections up to third order, quark mass…

Quadratic Mass Corrections of Order $α_{s}^{3} m_{q}^{2} / s$ to the Decay Rate of Z- and W- Bosons

K. G. Chetyrkin, J. H. Kuhn

We analytically compute quadratic mass corrections of order $α_{s}^{3} m_{q}^{2} / s$ to the absorptive part of the (non-diagonal) correlator of two axial vector currents. This allows us to…
