Chiral symmetry breaking by a non-Abelian external field in (2+1)-dimensions [PDF]

open access: yes, 1997
We investigate the effect of a constant external non-Abelian field on chiral symmetry breaking in a (2+1)-dimensional Nambu-Jona-Lasinio model and in 3D QCD by solving the gap equation and the Bethe-Salpeter equation, and also by RG analysis. In the (2+1)

Chiral symmetry breaking in brane models [PDF]

open access: yesJournal of High Energy Physics, 2008
We discuss the chiral symmetry breaking in general intersecting Dq/Dp brane models consisting of N_c Dq-branes and a single Dp-brane with an s-dimensional intersection. There exists a QCD-like theory localized at the intersection and the Dq/Dp model gives a holographic description of it.

Dyson-Schwinger Equation and Quantum Phase Transitions in Massless QCD [PDF]

open access: yes, 2006
We study the stability of the highest symmetric solution (Wigner-solution) of Dyson-Schwinger equations in chiral limit and at zero temperature. Our results confirm that if the chemical potential is not very large, the QCD vacuum is in the chiral ...

Photochemical Chiral Symmetry Breaking in Alanine [PDF]

open access: yesThe Journal of Physical Chemistry A, 2016
We introduce a general theoretical approach for the simulation of photochemical dynamics under the influence of circularly polarized light to explore the possibility of generating enantiomeric enrichment through polarized-light-selective photochemistry. The method is applied to the simulation of the photolysis of alanine, a prototype chiral amino acid.

Naturally Light Scalars [PDF]

open access: yes, 1995
I argue that in certain chiral gauge theories composite scalars associated with chiral symmetry breaking can be light (i.e. lighter than naive scaling from QCD would suggest) without any fine-tuning.

Minimally doubled fermions and spontaneous chiral symmetry breaking

open access: yesEPJ Web of Conferences, 2018
Chiral symmetry breaking in massless QCD is a very important feature in the current understanding of low energy physics. Low - lying Dirac modes are suitable to help us understand the spontaneous chiral symmetry breaking, since the formation of a non ...

Chiral symmetry breaking with lattice propagators [PDF]

open access: yesPhysical Review D, 2011
We study chiral symmetry breaking using the standard gap equation, supplemented with the infrared-finite gluon propagator and ghost dressing function obtained from large-volume lattice simulations. One of the most important ingredients of this analysis is the non-abelian quark-gluon vertex, which controls the way the ghost sector enters into the gap ...

Chiral symmetry breaking in the truncated Coulomb Gauge II. Non-confining power law potentials [PDF]

open access: yes, 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 ...
