Generalized Random Phase Approximation and Gauge Theories
Oliver Schroeder, Hugo Reinhardt
Mean-field treatments of Yang-Mills theory face the problem of how to treat the Gauss law constraint. In this paper we try to face this problem by studying the excited states inste…
Baryon Structure in a Covariant Diquark-Quark Model
G. Hellstern, R. Baürle, U. Zückert +2
The baryon structure is investigated in a covariant diquark-quark model. In this approach baryons emerge as relativistic bound states of a constituent quark and a or $1^{+}…
Strangeness content of the nucleon within the NJL soliton model
Abdellatif Abada, H. Weigel, R. Alkofer +1
We investigated the form factors of the nucleon associated with the nonet vector current in the framework of the generalized Yabu--Ando approach to the chiral soliton of the Nambu-…
Topologically non--trivial chiral transformations and their representations in a finite model space
R. Alkofer, H. Reinhardt, J. Schlienz +1
The role of chiral transformations in effective theories modeling Quantum Chromo Dynamics is reviewed. In the context of the Nambu--Jona--Lasinio model the hidden gauge and massive…
The chiral anomaly and electromagnetic pion decay in effective quark models
R. Alkofer, H. Reinhardt
Within renormalizable theories the triangle diagram correctly reproduces the lifetime of the neutral pion . However, effective relativistic quark models which contain a second…
