Optimized Lambda-Parametrization for the QCD Running Coupling Constant in Spacelike and Timelike Regions
A. V. Radyushkin
Abstract
The algorithm is described that enables one to perform an explicit summation of all the (π2/ ln(Q2/Lambda2))N corrections to αs (Q2) that appear owing to the analytic continuation from spacelike to timelike region of momentum transfer.
