Power corrections from short distances
G. Grunberg
It is argued that power contributions of short distance origin naturally arise in the infrared finite coupling approach. A phenomenology of power corrections is sketched.
1/Q^2 terms and Landau singularity
G. Grunberg
Standard power-behaved contributions in QCD arising from non-perturbative effects at low scale can be described, as shown by Dokshitzer, Marchesini and Webber, with the notion of a…
Power corrections and Landau singularity
G. Grunberg
In the dispersive approach of Dokshitzer, Marchesini and Webber, standard power-behaved contributions of infrared origin are described with the notion of an infrared regular QCD co…
Fixed points and power corrections
G. Grunberg
The connection between renormalons and power corrections is discussed in the case the effective coupling constant has an infrared fixed point of perturbative origin.
Renormalons and perturbative fixed points
Georges Grunberg
The connection between renormalons and power corrections is investigated for the typical infrared renormalon integral assuming the effective coupling constant has an infrared fixed…
