ABSTRACT
The color-flavor transformation is applied in the QCD strong coupling limit to construct the effective chiral Lagrangian. The calculations are performed by placing the fermions onto two different sub-lattices and by making use of the long-distance approximation and gradient expansion. The saddle point approximation could be applied on such a double lattice. In this framework the effect of the spontaneous chiral symmetry breaking is described and the numerical values of the chiral condensate, pion decay constant and pion mass are estimated by using the only parameter of model, the lattice spacing a. The effective chiral Lagrangian of QCD is recovered up to the terms of order O(p[sup 4]). © 2000 American Institute of Physics.

    It is shown that in the Nambu–Jona-Lasinio model with nonzero chemical potential there exist two different phases with spontaneous breaking of chiral symmetry and the transition between the phases is a second-order phase transition. The particle number density is nonzero in one phase and...

    We study meson (π,K) form factors in general, and specialize at a later stage to a specific scheme, namely the quark-level linear σ model (LσM). We compute a variety of electromagnetic and weak observables of light mesons, including pion and kaon form factors and charge radii,...

    We study how far the Index Theorem can be extrapolated from the continuum to finite lattices with finite topological charge densities. To examine how the Wilson action approximates the Index theorem, we specialize in the lattice version of the Schwinger model. We propose a new criterion for...

    We assume that QCD can be described in a certain kinematical regime by an effective string theory. This hadronic string must couple to background chiral fields in a chirally invariant manner, taking into account the true chirally non-invariant QCD vacuum. By requiring conformal symmetry of the...

    The N[SUBC] → ∞ limit of QCD gives a useful approximation scheme to the physical hadronic world. A brief overview of the mesonic sector is presented. The large-N[SUBC] constraints on the low-energy couplings of Chiral Perturbation Theory are summarized and the role of unitarity...

    We investigate chiral symmetry breaking and color symmetry breaking in QCD. The effective potential of the corresponding scalar condensates is discussed in the presence of non-perturbative contributions from the semiclassical one-instanton sector. We concentrate on a color singlet scalar...

    In the framework of chiral theories, we establish the interrelation between the responses of the nuclear medium to probes which couple either to the quark scalar density fluctuation ( i.e. the scalar susceptibility of quantum chromodynamics) or to the nucleonic ones. The second case concerns in...

    Light constituent quark masses and the corresponding dynamical quark masses are determined by data, the quark-level linear σ model, and infrared QCD. This allows to define effective nonstrange and strange current quark masses, which reproduce the experimental pion and kaon masses very...
