R(s) and Z decay in order αs4: complete results
Abstract
We report on our calculation of the order αs4 axial singlet contributions for the decay rates of the Z-boson as well as the vector singlet contribution to the cross section for electron-positron annihilation into hadrons. Together with recently finished O(αs4) calculations of the non-signlet corrections [1,2], the new results directly lead us to the first complete O(αs4) predictions for the total hadronic decay rate of the Z-boson and the ratio R(s).
