Vacuum replicas in field-theory models of Coulomb QCD
Pedro J. de A. Bicudo, Eduardo Garnacho Velasco, Felipe J. Llanes-Estrada +3
Dynamical symmetry breaking can happen through a Higgs mechanism but also spontaneously within a strongly-enough coupled theory. We treat a field-theoretical quark model of QCD bas…
Chiral symmetry and the properties of hadrons in the Generalised Nambu-Jona-Lasinio model
Yu. S. Kalashnikova, A. V. Nefediev, J. E. F. T. Ribeiro
Various aspects of the Generalised Nambu-Jona-Lasinio model for QCD in four dimensions are reviewed. The properties of mesonic excitations are discussed in detail, with special att…
Quark model with chiral-symmetry breaking and confinement in the Covariant Spectator Theory
Elmar P. Biernat, M. T. Peña, J. E. Ribeiro +2
We propose a model for the quark-antiquark interaction in Minkowski space using the Covariant Spectator Theory. We show that with an equal-weighted scalar-pseudoscalar structure fo…
Chiral-symmetry breaking and confinement in Minkowski space
Elmar P. Biernat, M. T. Peña, J. E. Ribeiro +2
We present a model for the quark-antiquark interaction formulated in Minkowski space using the Covariant Spectator Theory. The quark propagators are dressed with the same kernel th…
Chiral symmetry and pi-pi scattering in the Covariant Spectator Theory
Elmar P. Biernat, M. T. Peña, J. E. Ribeiro +2
The pi-pi scattering amplitude calculated with a model for the quark-antiquark interaction in the framework of the Covariant Spectator Theory (CST) is shown to satisfy the Adler ze…
Quark condensate for various heavy flavors
Dmitri Antonov, Jose Emilio F. T. Ribeiro
The quark condensate is calculated within the world-line effective-action formalism, by using for the Wilson loop an ansatz provided by the stochastic vacuum model. Starting with t…
