Confinement as crossover
Janos Polonyi
The order parameter of confinement together with the haaron model of the QCD vacuum is reviewed and it is pointed out that confining forces are generated by the non-renormalizable,…
Instanton Induced Phenomena in the Effective Standard Model
Vincenzo Branchina, Janos Polonyi
It is shown that in the Effective Standard Model new phenomena can arise due to the presence of small instanton configurations. The chief result is that under certain conditions ne…
Renormalization Group Analysis of the Heavy Field Decoupling in a Scalar Theory
A. Bonanno, J. Polonyi, D. Zappalá
The problem of two coupled scalar fields, one with mass much lighter than the other is analysed by means of Wilson's renormalization group approach. Coupled equations for the poten…
Confinement and renormalization
J. Polonyi
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 ex…
