Chiral Symmetry Breaking in QCD: A Variational Approach
We develop a “variational mass” expansion approach, recently introduced in the Gross–Neveu model, to evaluate some of the order parameters of chiral symmetry breakdown in QCD. The method relies on a reorganization of the usual perturbation theory with the addition of an arbitrary quark mass m, whose non-perturbative behaviour is inferred partly from renormalization group properties, and from an...
متن کاملRayleigh-Ritz Variational Approximation and Symmetry Nonrestoration
The investigation of symmetry nonrestoration scenarios has led to a controversy, with certain nonperturbative approximation schemes giving indications in sharp disagreement with those found within conventional perturbation theory. A Rayleigh-Ritz variational approach to the problem, which might be useful in bridging the gap between perturbative and nonperturbative viewpoints, is here proposed. ...
متن کاملChiral symmetry breaking in QCD Lite
A distinctive feature of the presence of spontaneous chiral symmetry breaking in QCD is the condensation of low modes of the Dirac operator near the origin. The rate of condensation must be equal to the slope of M πF 2 π/2 with respect to the quark mass m in the chiral limit, where Mπ and Fπ are the mass and the decay constant of the Nambu-Goldstone bosons. We compute the spectral density of th...
متن کاملChiral Symmetry Breaking in High Density QCD
We propose a symmetry breaking scheme for QCD with three massless quarks at high baryon density wherein the color and flavor SU(3)color×SU(3)L×SU(3)R symmetries are broken down to the diagonal subgroup SU(3)color+L+R by the formation of a condensate of quark Cooper pairs. We discuss general properties that follow from this hypothesis, including the existence of gaps for quark and gluon excitati...
متن کاملChiral-symmetry breaking in dual QCD.
In the context of the formulation of QCD with dual potentials, we show that chiral-symmetry breaking occurs only in the confined state. Therefore, the transition temperature, beyond which chiral symmetry is restored, is the same as the deconfinement temperature. To carry out the calculation, it is necessary to couple quarks to dual gluons. We indicate how this is done (to lowest order in the ma...
