Quark masses from quark-gluon condensates in a modified perturbative QCD

摘要

In this note, it is argued that the mass matrix for the six quarks can begenerated in first approximation by introducing fermion condensates on the samelines as was done before for gluons, within the modified perturbative expansionfor QCD proposed in former works. Thus, the results point in the direction ofthe conjectured link of the approximate `Democratic' symmetry of the quark massmatrix and `gap' effects similar to the ones occuring in superconductivity. Thecondensates are introduced here non-dynamically and therefore the question ofthe possibility for their spontaneous generation remains open. However,possible ways out of the predicted lack of the `Democratic' symmetry of thecondensates resulting from the spontaneous breaking of the flavour symmetry aresuggested. They come from an analysis based on the Cornwall--Jackiw--Tomboulis(CJT) effective potential for composite operators
