Confinement and renormalization
Abstract
Description
The haaron gas description is reviewed for the QCD vacuum. The role of non-renormalizable operators is emphasised in the mechanism which generates the string tension. Additional examples are mentioned where certain non-renormalizable operators of the bare lagrangian turn out to be important at finite energy scale.
