Five-Loop Running of the QCD coupling constant
P. A. Baikov, K. G. Chetyrkin, J. H. Kühn
We analytically compute the five-loop term in the beta function which governs the running of --- the quark-gluon coupling constant in QCD. The new term leads to a reduction o…
R(s) and Z decay in order α_s^4: complete results
P. A. Baikov, K. G. Chetyrkin, J. H. Kühn +1
We report on our calculation of the order α_s^4 axial singlet contributions for the decay rates of the Z-boson as well as the vector singlet contribution to the cross section for e…
Complete QCD Corrections to Hadronic --Decays in Order
P. A. Baikov, K. G. Chetyrkin, J. H. Kühn +1
Corrections of order for the axial singlet contributions for the decay rates of the -boson into hadrons are evaluated in the limit of the heavy top quark mass. Combined…
QCD Corrections to Hadronic Z and tau Decays
P. A. Baikov, K. G. Chetyrkin, J. H. Kuehn
We present a brief (mainly bibliographical) report on recently performed calculations of terms of order O(α_s^4 n_f^2) and O(α_s^4 n_f^2 m_q^2) for hadronic Z and τdecay rates. A f…
