Strangeness and Chiral Symmetry Breaking [PDF]

Mod.Phys.Lett.A26:279-288,2011, 2010
The implications of chiral symmetry breaking and SU(3) symmetry breaking have been studied in the chiral constituent quark model ($\chi$CQM). The role of hidden strangeness component has been investigated for the scalar matrix elements of the nucleon with an emphasis on the meson-nucleon sigma terms.

On Chiral Symmetry Restoration at Finite Density in Large N_c QCD [PDF]

Phys.Rev.C83:065201,2011, 2011
At large N_c, cold nuclear matter is expected to form a crystal and thus spontaneously break translational symmetry. The description of chiral symmetry breaking and translational symmetry breaking can become intertwined. Here, the focus is on aspects of chiral symmetry breaking and its possible restoration that are by construction independent of the ...

Chiral symmetry breaking by a non-Abelian external field in (2+1)-dimensions [PDF]

Phys.Rev. D57 (1998) 5230-5235, 1997
We investigate the effect of a constant external non-Abelian field on chiral symmetry breaking in a (2+1)-dimensional Nambu-Jona-Lasinio model and in 3D QCD by solving the gap equation and the Bethe-Salpeter equation, and also by RG analysis. In the (2+1)-dimensional NJL model chiral symmetry breaking occurs for any weak coupling constant but in 3D QCD

Chiral Symmetry Breaking with Scalar Confinement [PDF]

Phys.Rev. D70 (2004) 094047, 2003
Spontaneous chiral symmetry breaking is accepted to occur in low energy hadronic physics, resulting in the several successful theorems of PCAC. On the other hand scalar confinement is suggested both by the spectroscopy of hadrons and by the string picture of confinement.

Spontaneous Symmetry Breaking and Chiral Symmetry [PDF]

AIP Conference Proceedings, 2000
In this introductory lecture, some basic features of the spontaneous symmetry breaking are discussed. More specifically, $\sigma $-model, non-linear realization, and some examples of spontaneous symmetry breaking in the non-relativistic system are ...

Naturally Light Scalars [PDF]

Phys.Rev.D53:2284-2287,1996, 1995
I argue that in certain chiral gauge theories composite scalars associated with chiral symmetry breaking can be light (i.e. lighter than naive scaling from QCD would suggest) without any fine-tuning. These scalars will be even lighter in chiral gauge theories that produce chiral symmetry breaking without confinement.

Some Relations for Quark Confinement and Chiral Symmetry Breaking in QCD [PDF]

EPJ Web of Conferences, 2017
We analytically study the relation between quark confinement and spontaneous chiral-symmetry breaking in QCD. In terms of the Dirac eigenmodes, we derive some formulae for the Polyakov loop, its fluctuations, and the string tension from the Wilson loop ...

Nambu–Jona-Lasinio model in a parallel electromagnetic field

Physics Letters B, 2018
We explore the features of the UA(1) and chiral symmetry breaking of the Nambu–Jona-Lasinio model without the Kobayashi–Maskawa–'t Hooft determinant term in the presence of a parallel electromagnetic field. We show that the electromagnetic chiral anomaly

Gluon Condensates, Chiral Symmetry Breaking and Pion Wave Function [PDF]

Z.Phys. C58 (1993) 325-332, 1992
We consider here chiral symmetry breaking in quantum chromodynamics arising from gluon condensates in vacuum. Through coherent states of gluons simulating a mean field type of approximation, we show that the off-shell gluon condensates of vacuum generate a mass-like contribution for the quarks, giving rise to chiral symmetry breaking. We next note that
