Minimally doubled fermions and spontaneous chiral symmetry breaking
EPJ 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 ...

Influence of QED Corrections on the Orientation of Chiral Symmetry Breaking in the NJL model [PDF]
, 1966 We study QED corrections to chiral symmetry breaking in the Nambu--Jona-Lasinio (NJL) model with two flavors of quarks. In this model, the isospin symmetry is broken by the differences between the current quark masses and the electromagnetic charges of ...

Chiral symmetry breaking with lattice propagators [PDF]
Physical 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 ...

Role of U$_{A}$(1) breaking term in dynamical chiral symmetry breaking of chiral effective theories [PDF]
Prog. Theor. Exp. Phys. 2021, 093D02 (2021), 2019 The spontaneous breaking of chiral symmetry is examined by chiral effective theories, such as the linear sigma model and the Nambu Jona-Lasinio (NJL) model. Indicating that sufficiently large contribution of the UA(1) anomaly can break chiral symmetry spontaneously, we discuss such anomaly driven symmetry breaking and its implication.

Total Chiral Symmetry Breaking during Crystallization: Who needs a "Mother Crystal"? [PDF]
, 2005 Processes that can produce states of broken chiral symmetry are of particular interest to physics, chemistry and biology. Chiral symmetry breaking during crystallization of sodium chlorate occurs via the production of secondary crystals of the same ...

AAPPS Bulletin, 2021 After decades-long attempts to measure the mass shift and understand the origin of hadron mass, it became clear that one has to analyze hadrons with small vacuum width. Also, to identify the effect of chiral symmetry breaking, one has to start by looking

QCD, Symmetry Breaking and the Random Lattice [PDF]
Nucl.Phys.Proc.Suppl.140:698-700,2005, 2006 According to the Nielsen-Ninomiya No-Go theorem, the doubling of fermions on the lattice cannot be suppressed in a chiral theory. Whereas Wilson and staggered fermions suppress doublers with explicit breaking of chiral symmetry, the random lattice does so by spontaneous chiral symmetry breaking even in the free theory.

Catalysis of Dynamical Chiral Symmetry Breaking by Chiral Chemical Potential [PDF]
Phys. Rev. D 93, 105025 (2016), 2016 In this paper we study the properties of media with chiral imbalance parameterized by chiral chemical potential. It is shown that depending on the strength of interaction between constituents in the media the chiral chemical potential either creates or enhances dynamical chiral symmetry breaking.

Deconfinement, Chiral Symmetry Breaking and Chiral Polarization [PDF]
Proceedings of The 32nd International Symposium on Lattice Field Theory — PoS(LATTICE2014), 2015 We examine the feasibility of the proposition that there is a temperature range T$_c$ < T < T$_{ch}$ in N$_f$=0 QCD, where real Polyakov line (deconfined) vacuum exhibits valence spontaneous chiral symetry breaking and dynamical chiral polarization of Dirac eigenmodes.
