Pentaquarks in the Chiral Symmetry Limit [PDF]
Phys.Lett. B608 (2005) 59-63, 2004 We demonstrate that a five quark state of positive parity with an internal P-wave structure - usually pictured as a composite of an antiquark and two diquarks in a P-wave state - can couple to nucleons and Goldstone particles in a chirally invariant way. The corresponding decay width is generally not suppressed.

Confinement, chiral symmetry breaking and Faddeev–Niemi decomposition in QCD [PDF]
, 2001 We identify two distinct, complementary gauge field configurations for QCD with SU(2) gauge group, one (instanton-like configurations) having to do with chiral symmetry breaking but not with confinement, the other (regularized Wu-Yang monopoles) very ...

Chiral symmetry restoration at finite temperature in a model with manifest confinement [PDF]
Physics Letters BMultiple lattice evidences support the existence of a confining but chirally symmetric regime of QCD above the chiral symmetry restoration crossover at Tch≃155 MeV.

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

Nature Communications, 2022 External physical forces can bias a spontaneous symmetry breaking process but whether the shape of a reactor plays a role in chiral symmetry breaking processes is an open question. Here, the authors demonstrate chirality transfer from the chiral shape of

Chiral symmetry breaking on the lattice [PDF]
Progress in Particle and Nuclear Physics, 2017 We review important aspects of QCD in the continuum and on the lattice and take a look at the fate of its symmetries with an emphasis on chiral symmetry breaking on the lattice.

Non-Abelian anomalous constitutive relations of a chiral hadronic fluid [PDF]
EPJ Web of Conferences, 2022 We study the constitutive relations of a chiral hadronic fluid in presence of non-Abelian’t Hooft anomalies. Analytical expressions for the covariant currents are obtained at first order in derivatives in the chiral symmetric phase, for both two and ...

Chiral symmetry breaking in QCD [PDF]
Zeitschrift für Physik C Particles and Fields, 1987 By applying bifurcation theory to a truncated Dyson-Schwinger equation for the quark propagator in massless QCD, we show that dynamical symmetry breaking occurs at a certain critical value of the coupling constant. Essential ingredients are (a) an effective dynamical mass for the gluon, and (b) a running coupling constant.

Physical Review X, 2021 In principle, there is no obstacle to gapping fermions preserving any global symmetry that does not suffer a ’t Hooft anomaly. In practice, preserving a symmetry that is realized on fermions in a chiral manner necessitates some dynamics beyond simple ...
