Chiral symmetry restoration at finite temperature in a model with manifest confinement
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsMultiple lattice evidences support the existence of a confining but chirally symmetric regime of QCD above the chiral symmetry restoration crossover at Tch≃155 MeV.

Crystallization-driven template autocatalysis induces mirror symmetry breaking and amplification [PDF]
Nature CommunicationsA plausible hypothesis for the origin of biological homochirality invokes chiral symmetry breaking, transfer, and amplification driven by autocatalysis. Here we experimentally demonstrate that crystallization-driven template autocatalysis (CDTA) induces ...

Higher Structure of Chiral Symmetry. [PDF]
Commun Math PhysAbstract A recent development in our understanding of the theory of quantum fields is the fact that familiar gauge theories in spacetime dimensions greater than two can have non-invertible symmetries generated by topological defects. The hallmark of these non-invertible symmetries is that the fusion rule deviates from the usual group-like ...

Chiral Symmetry of Baryons [PDF]
Progress of Theoretical Physics, 2001 We study chiral symmetry aspects of the positive and negative parity baryons by identifying them with linear representations of the chiral group $SU(N_{f}) \otimes SU(N_{f})$. It is shown that there are two distinctive schemes: naive and mirror assignments.

Chiral symmetry restoration and N symmetry [PDF]
Physics Letters B, 1996 We demonstrate that chiral symmetry restoration in quenched finite temperature QCD depends crucially on the $Z_3$ phase of the Polyakov loop ${\cal P}$. This dependence is a general consequence of the coupling of the chiral order parameter to the Polyakov loop.

STRANGENESS AND CHIRAL SYMMETRY BREAKING [PDF]
Modern Physics Letters A, 2011 The implications of chiral symmetry breaking and SU(3) symmetry breaking have been studied in the chiral constituent quark model (χCQM). The role of hidden strangeness component has been investigated for the scalar matrix elements of the nucleon with an emphasis on the meson–nucleon sigma terms.

Symmetry-breaking in Chiral Polymerisation [PDF]
Origins of Life and Evolution of Biospheres, 2005 We propose a model for chiral polymerisation and investigate its symmetric and asymmetric solutions. The model has a source species which decays into left- and right-handed types of monomer, each of which can polymerise to form homochiral chains; these chains are susceptible to `poisoning' by the opposite handed monomer. Homochiral polymers are assumed

Fate of the ρ – a1 mixing in dilepton production [PDF]
EPJ Web of ConferencesWe investigate the effect of chiral mixing on dilepton production by combining the in-medium spectral function in the chiral effective field theory with the state-of-the-art fluid dynamical simulations.

CHIRAL SYMMETRY AND PENTAQUARKS [PDF]
Pentaquark 04, 2005 Spontaneous chiral symmetry breaking, mesons and baryons are illustrated in the language of the Dirac theory. Various forces acting between quarks inside baryons are discussed. I explain why the naive quark models typically overestimate pentaquark masses by some 500 MeV and why in the fully relativistic approach to baryons pentaquarks turn out to be ...
