Phase structure of NJL model with finite quark mass and QED correction [PDF]
, 2007 We study QED corrections to the chiral symmetry breaking in Nambu-Jona-Lasinio (NJL) model with two flavors of quarks. In the model the isospin symmetry is broken by differences of the current quark masses and the electromagnetic charges between up and ...

A Master Formula for Chiral Symmetry Breaking [PDF]
Annals of Physics, 1996 We derive a master formula for chiral $SU(2)\times SU(2)$ breaking, based on the Veltman-Bell equations and the Peierls-Dyson relation. Our approach does not rely on the use of the soft pion limit or an expansion around the chiral limit, and yields exact results for on-shell pions. Threshold theorems for $ N\rightarrow N$, $ N\rightarrow N$, $ N\

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 ...

, 2010 We study in detail the effect of the finite current quark mass on chiral symmetry breaking, in the framework of truncated Coulomb gauge QCD with a linear confining quark-antiquark potential. In the chiral limit of massless current quarks, the breaking of

Phys.Rev.D83:065006,2011, 2010 Schwinger-Dyson equations are used to study spontaneous chiral and parity symmetry breaking of three dimensional quantum electrodynamics with two-component fermions. This theory admits a topological photon mass that explicitly breaks parity symmetry and generates a fermion mass.

Abelian dominance in chiral symmetry breaking [PDF]
Nuclear Physics B - Proceedings Supplements, 1996 Calculations of the chiral condensate $\langle \bar \rangle$ on the lattice using staggered fermions and the Lanczos algorithm are presented. Three gauge fields are considered: the quenched non-Abelian field, the Abelian field projected in the maximal Abelian gauge, and the monopole field further decomposed from the Abelian field.

Chiral symmetry breaking in the truncated Coulomb Gauge II. Non-confining power law potentials
, 2008 In this paper we study the breaking of chiral symmetry with non-confining power-like potentials. The region of allowed exponents is identified and, after the previous study of confining (positive exponent) potentials, we now specialize in shorter range ...

Four-fermion deformations of the massless Schwinger model and confinement
Journal of High Energy Physics, 2023 We consider the massless charge-N Schwinger model and its deformation with two four-fermion operators. Without the deformations, this model exhibits chiral symmetry breaking without confinement. It is usually asserted that the massless Schwinger model is
