Isospin Mass Splittings and the $\ms$ Corrections in the Semibosonized SU(3)-NJL-Model
Andree Blotz, K. Goeke, M. Praszalowicz
The mass splittings of hyperons including the isospin splittings are calculated with $O(\ms^2)$ and $O(\ms \dm)$ accuracy respectively within the semibosonized SU(3)-NJL model. The…
Hyperon in Chiral Effective Quark Models
A. Blotz, M. Praszalowicz, K. Goeke
Baryonic correlation functions are calculated within an effective chiral quark model motivated by the instanton liquid model of QCD. Using a flavour SU(3) symmetry for the local fo…
Loop corrections to the sphaleron transition rate in the minimal standard model
Dmitri Diakonov, Maxim Polyakov, Pavel Pobylitsa +3
The baryon number dissipation rate due to sphaleron transitions at high temperatures in the minimal standard model is evaluated. We find that this rate can be considerably suppress…
Electromagnetic Nucleon Properties and Quark Sea Polarization
Chr. V. Christov, A. Z. Górski, K. Goeke +1
In this paper we present the derivation as well as the numerical results for all electromagnetic form factors of the nucleon within the chiral quark soliton model in the semiclassi…
Axial Properties of the Nucleon with -Corrections in the solitonic SU(3)-NJL-Model
A. Blotz, M. Praszalowicz, K. Goeke
Within the semibosonized SU(3)-NJL model the mass splittings of baryons and the axial vector coupling constants of the nucleon are evaluated. The mass splittings of the hyperons ar…
