Axial properties of the nucleon with 1 / N c corrections in the solitonic SU ( 3 ) - NJL - model
نویسنده
چکیده
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 are reproduced with great accuracy if second order corrections in ms are taken into account. email:[email protected] email:[email protected] email:[email protected]

Baryons as Chiral solitons in the Nambu– Jona-Lasinio model
y Supported in part by the Deutsche Forschungsgemeinschaft (DFG) under contract number Re{856/2-2. z Supported by a Habilitanden{scholarship of the Deutsche Forschungsgemeinschaft (DFG). Abstract The description of baryons as chiral solitons of the Nambu{Jona{Lasinio (NJL) model is reviewed. A motivation for the soliton description of baryons is provided from large N C QCD. Rigorous results on ...
متن کاملNote on Strange Quarks in the Nucleon
Scalar matrix elements involving strange quarks are studied in several models. Apart from a critical reexamination of results obtained in the Nambu and Jona-Lasinio model we study a scenario, motivated by instanton physics, where spontaneous chiral symmetry breaking is induced by the flavor-mixing ’t Hooft interaction only. We also investigate possible contributions of virtual kaon loops to the...
متن کاملPion Properties in the 1 / N c - corrected NJL model
We investigate the effect of mesonic fluctuations on the pion propagator in the Nambu–Jona-Lasinio (NJL) model by explicitly taking into account 1/N c-corrections. Because of the non-renormalizability of the model we have to regularize the meson loops with an independent cutoff parameter Λ M. Whereas for moderate values of Λ M the properties of the pion change only quantitatively we encounter s...
متن کاملThermodynamic Properties of the SU ( 2 ) f Chiral Quark – Loop Soliton
We consider a chiral one-loop hedgehog soliton of the bosonized SU(2) f Nambu & Jona-Lasinio model which is embedded in a hot medium of constituent quarks. Energy and radius of the soliton are determined in self-consistent mean-field approximation. Quasi-classical corrections to the soliton energy are derived by means of the pushing and cranking approaches. The corresponding inertial parameters...

The electromagnetic form factors of the SU(3) octet baryons are investigated in the semibosonized SU(3) Nambu–Jona-Lasinio model (chiral quark-soliton model). The rotational 1/N c and strange quark mass corrections in linear order are taken into account. The electromagnetic charge radii of the nucleon and magnetic moments are also evaluated. It turns out that the model is in * 1 a remarkable go...
