Dilaton and Chiral-Symmetry Breaking
Physical Review Letters, 1986The spontaneous breaking of chiral symmetry in certain gauge models may also imply the spontaneous breaking of an approximate scale symmetry. This breaking will produce the dilaton as a pseudo-Goldstone boson of spontaneously broken scale invariance.

Spontaneous Breakings of Chiral Symmetries
Physical Review D, 1970We analyze in detail the spontaneous breakings of chiral $\mathrm{SU}(3)\ensuremath{\bigotimes}\mathrm{SU}(3)$ and $\mathrm{SU}(2)\ensuremath{\bigotimes}\mathrm{SU}(2)$. We determine the directions along which the two groups may break spontaneously.

Quark confinement and chiral-symmetry breaking [PDF]
Il Nuovo Cimento A, 1984 In the framework of non-Abelian gauge theories, having a confining gauge field propagator infra-red singular like 1/q4, we show that the full apparatus of the Schwinger-Dyson equations in the Landau gauge is consistent only if there is a solution of the self-mass equation which i) introduces a break down of the chiral symmetry and ii) gives an infrared

Nuclear Physics A, 1992
Abstract Recent developments related to chiral symmetry and its explicit breaking by quark masses are summarized. We discuss the status of the pion-nucleon sigma term and questions of threshold π° photoproduction.

Breaking chiral symmetry in a solid
Science, 2015Topological Matter Dirac semimetals have graphene-like electronic structure, albeit in three rather than two dimensions. In a magnetic field, their Dirac cones split into two halves, one supporting left-handed and the other right-handed fermions.

On chiral symmetry breaking. II
Annals of Physics, 1973Abstract We study the restrictions imposed on chiral symmetry breaking terms by a set of postulates, whose main content is furnished by certain ideas of Michel and Radicati. We then test certain particular cases by utilizing an effective Lagrangian and calculating meson-meson scattering lengths.

Spontaneous breaking of chiral symmetries
Il Nuovo Cimento A, 1979The spontaneous breaking of chiralU 3×U 3 symmetry down toU 1×U 1×U 1 is studied from the in-field point of view. It is shown that the original symmetry undergoes a dynamical rearrangement and thus the observational symmetry,i.e. the symmetry of in-fields, assumes a totally different structure from that of the Heisenberg fields. As its application, the

On the breaking of chiral gauge symmetry
Nuclear Physics B - Proceedings Supplements, 1990Abstract It is conjectured that the lack of chiral gauge symmetry-preserving regulator is signalling a genuine quantum effect which breaks chiral gauge symmetries and generates masses for gauge bosons. This idea is applied to an SU(3) C ×SU(2) L ×U(1) Y model. It is shown that the dynamics of chiral fermions can generate masses for the W and Z
