The problem of precise evaluation of perturbative QCD predictions at moderate energies is addressed. In order to improve stability of the predictions with respect to change of the renormalization scheme it is proposed to replace the sequence of conventional renormalization group improved approximants by a sequence of modified approximants, involving a modified running coupling constant, which is free from Landau singularity and much less renormalization scheme depenedent than the conventional… CONTINUE READING
