STRANGENESS AND CHIRAL SYMMETRY BREAKING [PDF]

Modern Physics Letters A, 2011
The implications of chiral symmetry breaking and SU(3) symmetry breaking have been studied in the chiral constituent quark model (χCQM). 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.

Confinement, chiral symmetry breaking and the mass generation of hadrons [PDF]

arXiv, 2012
A key question to QCD is what mechanism generates the hadron mass in the light quark sector, where both confinement and chiral symmetry breaking are in the game. Are confinement and chiral symmetry breaking in the vacuum uniquely interconnected? Can hadrons survive chiral symmetry restoration?

Conformal symmetry and the chiral anomaly [PDF]

Physical Review D, 1997
Two-loop contributions to the anomalous correlation function of three chiral currents are calculated by a method based on the conformal properties of massless field theories. The method was previously applied to virtual photon diagrams in quantum electrodynamics, and it is extended here to diagrams with scalars and chiral spinors in the abelian Higgs ...

Aspects of chiral symmetry and the lattice [PDF]

Reviews of Modern Physics, 2001
I explore the non-perturbative issues entwining lattice gauge theory, anomalies, and chiral symmetry. After briefly reviewing the importance of chiral symmetry in particle physics, I discuss how anomalies complicate lattice formulations. Considerable information can be deduced from effective chiral Lagrangians, helping interpret the expectations for ...

Effective Chiral theory of Mesons [PDF]

arXiv, 1996
The meson fields are simulated by quark operators and an effective chiral theory of mesons is presented. There are spontaneous chiral symmetry breaking and dynamical chiral symmetry breaking. Theoretical results agree with data well.

Understanding chiral charge-density wave by frozen chiral phonon [PDF]

Zhang, S., Luo, K. & Zhang, T. Understanding chiral charge-density wave by frozen chiral phonon. npj Comput Mater 10, 264 (2024)
Charge density wave (CDW) is discovered within a wide interval in solids, however, its microscopic nature is still not transparent in most realistic materials, and the recently studied chiral ones with chiral structural distortion remain unclear. In this paper, we try to understand the driving forces of chiral CDW transition by chiral phonons from the ...

Chiral symmetry in lattice QCD [PDF]

Nuclear Physics B - Proceedings Supplements, 2001
A chiral invariant effective action for lattice QCD is proposed. Its connection to the multifermion model is established. A possibility of using this action for computer simulations is discussed.
