Thermal Restoration of Chiral Symmetry in Supersymmetric Nambu-Jona-Lasinio Model with Soft SUSY Breaking [PDF]
, 1998 The supersymmetric version of the Nambu-Jona-Lasinio model is investigated in connection with the chiral symmetry breaking induced by a soft SUSY breaking term.

On the symmetry breaking phenomenon [PDF]
, 2006 We investigate the problem of symmetry breaking in the framework of dynamical systems with symmetry on a smooth manifold. Two cases will be analyzed: general and Hamiltonian dynamical systems.

Spontaneous breaking of spatial and spin symmetry in spinor condensates [PDF]
, 2010 Parametric amplification of quantum fluctuations constitutes a fundamental mechanism for spontaneous symmetry breaking. In our experiments, a spinor condensate acts as a parametric amplifier of spin modes, resulting in a twofold spontaneous breaking of ...

Breaking embryo symmetry [PDF]
Science, 2017 Embryogenesis![Figure][1] Loss of cleavage symmetry in the early embryo PHOTO: E. KOROTKEVICH ET AL., DEV. CELL 40 , 235 (6 FEBRUARY 2017) © ELSEVIER For the first few cleavages, cells of the mammalian embryo are considered identical. Subsequently, symmetry is broken to generate the inner cell mass, which specifies the embryo proper, or the ...

Symmetry breaking on density in escaping ants: experiment and alarm pheromone model.
PLoS ONE, 2014 The symmetry breaking observed in nature is fascinating. This symmetry breaking is observed in both human crowds and ant colonies. In such cases, when escaping from a closed space with two symmetrically located exits, one exit is used more often than the

Lepton and quark masses and mixing in a SUSY model with Δ(384) and CP
Nuclear Physics B, 2020 We construct a supersymmetric model for leptons and quarks with the flavor symmetry Δ(384) and CP. The peculiar features of lepton and quark mixing are accomplished by the stepwise breaking of the flavor and CP symmetry. The correct description of lepton

Gauged Peccei-Quinn symmetry — A case of simultaneous breaking of SUSY and PQ symmetry
Journal of High Energy Physics, 2018 Recently, a simple prescription to embed the global Peccei-Quinn (PQ) symmetry into a gauged U(1) symmetry has been proposed. There, explicit breaking of the global PQ symmetry expected in quantum gravity are highly suppressed due to the gauged PQ ...

Probing the electroweak symmetry breaking history with gravitational waves
Journal of High Energy Physics, 2023 We perform three dimensional lattice simulation of the electroweak symmetry breaking process through two-step vacuum-like phase transitions with one step being first-order. Our results show that: 1) when the electroweak symmetry breaking is driven by the
