Electromagnetic nucleon properties and quark sea polarization in the Nambu-Jona-Lasinio model

A. Z. Gorski, Chr. V. Christov, K. Goeke

In this paper we present the derivation as well as the numerical results for all electromagnetic form factors of the nucleon within the semibosonized Nambu--Jona-Lasinio (chiral qu…

Rotational Corrections to and Isovector Magnetic Moment of the Nucleon

Chr. V. Christov, K. Goeke, P. Pobilitsa +3

The rotational corrections to the axial vector constant and the isovector magnetic moment of the nucleon are studied in the Nambu -- Jona-Lasinio model. We follow a semicla…

Electric Polarizability of the Nucleon in the Nambu--Jona-Lasinio Model

E. Nikolov, W. Broniowski, K. Goeke

The electric polarizability of the nucleon is calculated in the soliton approach to the Nambu--Jona-Lasinio model. We analyze the leading- contributions, as well as the effect…

On Size and Shape of the Average Meson Fields in the Semibosonized Nambu & Jona-Lasinio Model

R. Wuensch, K. Goeke, Th. Meissner

We consider a two-flavor Nambu \& Jona-Lasinio model in Hartree approximation involving scalar-isoscalar and pseudoscalar-isovector quark-quark interactions. Average meson fields a…

On discrete Zariski-dense subgroups of algebraic groups

J. Winkelmann

We investigate for which linear-algebraic groups (over the complex numbers or any local field) there exists subgroups which are dense in the Zariski topology, but discrete in the H…

Fermion sea along the sphaleron barrier

Dmitri Diakonov, Maxim Polyakov, Peter Sieber +2

In this revised version we have improved the treatment of the top and bottom quark mass. This leads to slight changes of the numerical results, especially of those presented in Fig…
