Symplectic reduction and the problem of time in nonrelativistic mechanics [PDF]
, 2010 Symplectic reduction is a formal process through which degeneracy within the mathematical representations of physical systems displaying gauge symmetry can be controlled via the construction of a reduced phase space. Typically such reduced spaces provide

Dark discrete gauge symmetries [PDF]
Physical Review D, 2011 We investigate scenarios in which dark matter is stabilized by an abelian Z_N discrete gauge symmetry. Models are surveyed according to symmetries and matter content. Multi-component dark matter arises when N is not prime and Z_N contains one or more subgroups.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

Residual gauge symmetry and color confinement in the Yang–Mills theory
Nuclear Physics BWe examine the restoration of the residual gauge symmetry in the Yang–Mills theory to be regarded as a confinement criterion. For this purpose, we restrict the four-dimensional SU(2) Yang–Mills instantons to those with spatial spherical symmetry SO(3 ...

Gauge invariance and holographic renormalization
Physics Letters B, 2015 We study the gauge invariance of physical observables in holographic theories under the local diffeomorphism. We find that gauge invariance is intimately related to the holographic renormalization: the local counter terms defined in the boundary cancel ...

Degrees of Metastability in Gauge Mediated Supersymmetry Breaking [PDF]
, 2011 This thesis consists of an investigation into supersymmetry and its breaking. Emphasis is placed on the question of metastability and the role of non-topological solitons in the hidden sector.

Gauge symmetries on θ-deformed spaces [PDF]
Journal of High Energy Physics, 2007 A Hamiltonian formulation of gauge symmetries on noncommutative ($θ$ deformed) spaces is discussed. Both cases- star deformed gauge transformation with normal coproduct and undeformed gauge transformation with twisted coproduct- are considered. While the structure of the gauge generator is identical in either case, there is a difference in the ...

Vector dark matter from a gauged SU(2) symmetry
Journal of High Energy Physics, 2021 We propose a scenario of dark sector described by a hidden SU(2) gauge symmetry which is broken by a vacuum expectation value(VEV) of a scalar multiplet.

Semiclassical monopole calculations in supersymmetric gauge theories [PDF]
, 2000 We investigate semiclassical contributions to correlation functions in N = 1 supersymmetric gauge theories. Our principal example is the gluino condensate, which signals the breaking of chiral symmetry, and should be exactly calculable, according to a ...
