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

Baryons and chiral symmetry [PDF]
International Journal of Modern Physics E, 2017 The relevance of chiral symmetry in baryons is highlighted in three examples in the nucleon spectroscopy and structure. The first one is the importance of chiral dynamics in understanding the Roper resonance. The second one is the role of chiral symmetry in the lattice calculation of [Formula: see text] term and strangeness.

Quantum gravity and Standard-Model-like fermions
Physics Letters B, 2017 We discover that chiral symmetry does not act as an infrared attractor of the renormalization group flow under the impact of quantum gravity fluctuations. Thus, observationally viable quantum gravity models must respect chiral symmetry. In our truncation,

Spontaneous symmetry breaking and chiral symmetry [PDF]
AIP Conference Proceedings, 2000 In this introductory lecture, some basic features of the spontaneous symmetry breaking are discussed. More specifically, $σ$-model, non-linear realization, and some examples of spontaneous symmetry breaking in the non-relativistic system are discussed in details.

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 ...

Heavy–light mesons in chiral AdS/QCD
Physics Letters B, 2017 We discuss a minimal holographic model for the description of heavy–light and light mesons with chiral symmetry, defined in a slab of AdS space. The model consists of a pair of chiral Yang–Mills and tachyon fields with specific boundary conditions that ...

’t Hooft anomaly matching condition and chiral symmetry breaking without bilinear condensate
Journal of High Energy Physics, 2019 We explore 4-dimensional SU(N) gauge theory with a Weyl fermion in an irreducible self-conjugate representation. This theory, in general, has a discrete chiral symmetry.

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 ...

Symmetry-protected solitons and bulk-boundary correspondence in generalized Jackiw–Rebbi models
Scientific Reports, 2021 We investigate the roles of symmetry and bulk-boundary correspondence in characterizing topological edge states in generalized Jackiw–Rebbi (JR) models.

Chiral symmetry restoration with three chiral partners
SciPost Physics Proceedings, 2022 I discuss the masses of chiral partners in the context of chiral symmetry restoration at finite temperature. Using the Nambu–Jona-Lasinio model I first remind the usual situation where two mesons of opposed parity become degenerate above the chiral ...
