Spectroscopy and renormalization group flow of a lattice Nambu-Jona-Lasinio model.

چکیده
We investigate a lattice Nambu–Jona-Lasinio model both by the Monte Carlo method and Schwinger-Dyson equations. A comparison allows the discussion of finite size effects and the extrapolation to infinite volume. We pay special attention to the identification of particles and resonances. This enables us to discuss renormalisation group flows in the neighbourhood of the critical coupling where the chiral symmetry breaking phase transition takes place. In no region of the bare parameter space do we find renormalisability for the model. DESY 93-195 ISSN 0418-9833 FUB-HEP/93-14 HLRZ-93-51 December 1993

Renormalization flow of bound states
A renormalization group flow equation with a scale-dependent transformation of field variables gives a unified description of fundamental and composite degrees of freedom. In the context of the effective average action, we study the renormalization flow of scalar bound states which are formed out of fundamental fermions. We use the gauged Nambu–Jona-Lasinio model at weak gauge coupling as an ex...

Using the Nambu–Jona-Lasinio (NJL) model we study responses of the pion and kaon masses to changes in the chemical potential, ∂m ∂μ , at zero and finite chemical potential. We find that the behavior of ∂m ∂μ for the pion is quite different from that for the kaon. Our results can give a clue for future studies of ∂m ∂μ on the lattice.

We investigate the modifications of mesonic properties in a hot medium having in mind to use the mesonic modes as a tool to analyze the restoration of chiral and axial symmetries in the context of the SU(3) Polyakov–Nambu–Jona-Lasinio (PNJL) model. The results lead to the conclusion that the effects of the Polyakov loop are fundamental for reproducing lattice findings. It is found that the rest...

متن کاملSpontaneous Breaking of Flavor Symmetry and Parity in the Nambu-Jona-Lasinio Model with Wilson Fermions
We study the lattice Nambu-Jona-Lasinio model with two flavors of Wilson fermions in the large N limit, where N is the number of ‘colors’. For large values of the fourfermion coupling we find a phase in which both, flavor symmetry and parity, are spontaneously broken. In accordance with general expectations there are three massless pions on the phase boundary, but only two of them remain massle...
