Lack Of Knowledge

The frozen QCD coupling is a parameter often used as an effective fixed coupling. It is supposed to mimic both the running coupling effects and the lack of knowledge of αs in the infrared region. Usually the value of the frozen coupling is fixed from the analysis of the experimental data. A novel way to define such coupling(s) independently of the experiments is presented. We argue that there are different frozen couplings which are used in the double-logarithmic (DL) and single-logarithmic (SL) approximations. They also differ for space- and time-like arguments. Our estimates are in a good agreement with the results available in the literature.
