Dynamical Symmetry Breaking on Langevin Equation : Nambu · Jona - Lasinio Model
نویسنده
چکیده
In order to investigate dynamical symmetry breaking, we study Nambu·JonaLasinio model in the large-N limit in the stochastic quantization method. Here in order to solve Langevin equation, we impose specified initial conditions and construct “effective Langevin equation” in the large-N limit and give the same non-perturbative results as path-integral approach gives. Moreover we discuss stability of vacuum by means of “effective potential”.

Thermal Restoration of Chiral Symmetry in Supersymmetric Nambu-Jona-Lasinio Model with Soft SUSY Breaking
The supersymmetric version of the Nambu-Jona-Lasinio model is investigated in connection with the chiral symmetry breaking induced by a soft SUSY breaking term. It is found that the broken chiral symmetry due to the soft breaking term is restored at suitably high temperature and the symmetry restoration occurs as first-order phase transitions. The critical temperature at which the chiral symmet...
متن کاملDimensional Reduction in Nambu – Jona – Lasinio Model in External Chromomagnetic Field
The effective dimensional reduction of fermion-antifermion pairing dinam-ics in Nambu-Jona-Lasinio model in external chromomagnetic field is considered. It is shown that such a field causes the reduction of the space dimension by one unit in contrast to an ordinary magnetic field which reduces it by two units. The enhancement of the dynamical chiral symmetry breaking due to the reduction is dis...
متن کاملThe Nambu-Jona Lasinio mechanism and electroweak symmetry breaking in the Standard Model
In this paper I examine the breaking of internal symmetries from another point of view showing that is possible to reproduce the electroweak panorama of the traditional Standard Model in a exhaustive and self consistent way. The result is reached applying the main futures of the old Nambu-Jona Lasinio (NJL) mechanism to an electroweak invariant Lagrangian. In this context the use of functional ...
متن کاملElectroweak Symmetry Breaking via a Technicolor Nambu–Jona-Lasinio Model
We consider a theory of gauge fields and fermions which we argue gives rise to dynamics similar to that of the Nambu–Jona-Lasinio (NJL) model when a gauge coupling constant is appropriately fine-tuned. We discuss the application of this model to dynamical electroweak symmetry breaking by a top-quark condensate. In this model, custodial symmetry is violated solely by perturbatively weak interact...
متن کاملDynamical symmetry breaking in the external gravitational and constant magnetic fields
We investigate the effects of the external gravitational and constant magnetic fields to the dynamical symmetry breaking. As simple models of the dynamical symmetry breaking we consider the Nambu-Jona-Lasinio (NJL) model and the supersymmetric Nambu-Jona-Lasinio (SUSY NJL) model non-minimally interacting with the external gravitational field and minimally interacting with constant magnetic fiel...
