Infrared and Ultraviolet Coupling in Qcd
نویسنده
چکیده
The coupled Dyson-Schwinger equations for the gluon and ghost propagators in QCD are shown to have solutions that correspond to a unique running coupling that has a nite infrared xed point and the expected logarithmic decrease in the ultraviolet. The infrared coupling is large enough to support chiral symmetry breaking; and quarks are not connned, but they cannot be isolated.

Conformal window and Landau singularities
A physical characterization of Landau singularities is emphasized, which should trace the lower boundary N∗ f of the conformal window in QCD and supersymmetric QCD. A natural way to disentangle “perturbative” from “non-perturbative” contributions below N∗ f is suggested. Assuming an infrared fixed point is present in the perturbative part of the QCD coupling even in some range below N∗ f leads ...

A mass scale µc representing the boundary between effective theories of strong interactions and perturbative QCD (infrared and ultraviolet regimes) exists when the β-function is characterized by a simple pole. This behaviour, which is known to occur in N = 1 supersymmetric Yang-Mills theories, leads to an infrared attractor in the evolution of the coupling constant, with the mass scale µc of th...
