Centre vortex removal restores chiral symmetry [PDF]
, 2017 The influence of centre vortices on dynamical chiral symmetry breaking is investigated through the light hadron spectrum on the lattice. Recent studies of the quark propagator and other quantities have provided evidence that centre vortices are the ...

Interacting fermions in rotation: chiral symmetry restoration, moment of inertia and thermodynamics [PDF]
Journal of High Energy Physics, 2016 We study rotating fermionic matter at finite temperature in the framework of the Nambu-Jona-Lasinio model. In order to respect causality the rigidly rotating system must be bound by a cylindrical boundary with appropriate boundary conditions that confine

CHIRAL SYMMETRY ON THE LATTICE [PDF]
, 2005 As a non-perturbative and gauge invariant regularization the lattice provides a tool for deeper understanding of the celebrated Yang-Mills theory, QCD and chiral gauge theories. For illustration, I discuss some analytic developments on the lattice related to chiral symmetry, chiral fermions and improvement programs.

Chiral Symmetry and Scalars [PDF]
AIP Conference Proceedings, 2002 The suggestion by Jaffe that if $ $ is a light $q^{2}\bar{q}^{2}$ state $0^{++}$ then even the fundamental chiral transformation properties of the $ $ becomes {\bf unclear}, has stimulated much interest. Adler pointed out that in fact the seminal work on chiral symmetry via PCAC consistency, is really quite consistent with the $ $ being ...

On the Bose symmetry and the left- and right-chiral anomalies
European Physical Journal C: Particles and Fields, 2018 It is generally assumed that in order to preserve Bose symmetry in the left- (or right-chiral) current it is necessary to equally distribute the chiral anomaly between the vectorial and the axial Ward identities, requiring the use of counterterms to ...

Chiral symmetry restoration in heavy-ion collisions at intermediate energies [PDF]
, 2016 We study the effect of the chiral symmetry restoration (CSR) on heavy-ion collisions observables in the energy range $\sqrt{s_{NN}}$=3-20 GeV within the Parton-Hadron-String Dynamics (PHSD) transport approach.

η' meson under partial restoration of chiral symmetry in nuclear medium*
EPJ Web of Conferences, 2012 We shed light upon the η' mass in nuclear matter in the context of partial restoration of chiral symmetry, pointing out that the UA(1) anomaly effects causes the η'-η mass difference necessarily through the chiral symmetry breaking.

The computational challenge of lattice chiral symmetry - Is it worth the expense? [PDF]
EPJ Web of Conferences, 2020 The origin of the low-lying position of the Roper resonance in the nucleon energy spectrum has been the subject of significant interest for many years, including several investigations using lattice QCD.

Chiral symmetry breaking in three-dimensional quantum electrodynamics as fixed point annihilation [PDF]
, 2016 Spontaneous chiral symmetry breaking in three-dimensional ($d=3$) quantum electrodynamics is understood as annihilation of an infrared-stable fixed point that describes the large-N conformal phase by another unstable fixed point at a critical number of ...
