Pentaquarks in the Chiral Symmetry Limit [PDF]
Phys.Lett. B608 (2005) 59-63, 2004 We demonstrate that a five quark state of positive parity with an internal P-wave structure - usually pictured as a composite of an antiquark and two diquarks in a P-wave state - can couple to nucleons and Goldstone particles in a chirally invariant way. The corresponding decay width is generally not suppressed.

Symmetries of hadrons after unbreaking the chiral symmetry [PDF]
Phys. Rev. D 86 (2012) 014507, 2012 We study hadron correlators upon artificial restoration of the spontaneously broken chiral symmetry. In a dynamical lattice simulation we remove the lowest lying eigenmodes of the Dirac operator from the valence quark propagators and study evolution of the hadron masses obtained.

’t Hooft anomaly matching condition and chiral symmetry breaking without bilinear condensate [PDF]
Journal of High Energy Physics, 2019 We explore 4-dimensional SU(N) gauge theory with a Weyl fermion in an irreducible self-conjugate representation. This theory, in general, has a discrete chiral symmetry.

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 ...

Bose-Einstein condensation and chiral phase transition in linear sigma model [PDF]
J.Phys. G31 (2005) 459-470, 2005 With the linear sigma model, we have studied Bose-Einstein condensation and the chiral phase transition in the chiral limit for an interacting pion system. A $\mu-T$ phase diagram including these two phenomena is presented. It is found that the phase plane has been divided into three areas: the Bose-Einstein condensation area, the chiral symmetry ...

Consequences of the partial restoration of chiral symmetry in AdS/QCD [PDF]
Phys.Rev.D77:096011,2008, 2008 Chiral symmetry is an essential concept in understanding QCD at low energy. We treat the chiral condensate, which measures the spontaneous breaking of chiral symmetry, as a free parameter to investigate the effect of partially restored chiral symmetry on the physical quantities in the frame work of an AdS/QCD model.

Baryons and Chiral Symmetry [PDF]
International Journal of Modern Physics E, 2016 The relevance of chiral symmetry in baryons is highlighted in three examples in the nucleon spectroscopy and structure. The first one is the importance of chiral dynamics in understanding the Roper resonance. The second one is the role of chiral symmetry

Catalysis of Dynamical Chiral Symmetry Breaking by Chiral Chemical Potential in Dirac semimetals [PDF]
Physical review B, 2019 In this paper we study how dynamical chiral symmetry breaking is affected by nonzero chiral chemical potential in Dirac semimetals. To perform this study we applied lattice quantum Monte Carlo simulations of Dirac semimetals. Within lattice simulation we
