arXiv, 2023 The gauge symmetry is said unfree if the gauge transformation leaves the action functional unchanged provided for the gauge parameters are constrained by the system of partial differential equations. The best known example of this phenomenon is the volume preserving diffeomorphism being the gauge symmetry of unimodular gravity (UG).

Gauge origin of discrete flavor symmetries in heterotic orbifolds [PDF]
Physics Letters B, 2014 We show that non-Abelian discrete symmetries in orbifold string models have a gauge origin. This can be understood when looking at the vicinity of a symmetry enhanced point in moduli space.

Gauge-Higgs Unification Models in Six Dimensions with S2/Z2 Extra Space and GUT Gauge Symmetry [PDF]
Advances in High Energy Physics, 2012 We review gauge-Higgs unification models based on gauge theories defined on six-dimensional spacetime with S2/Z2 topology in the extra spatial dimensions. Nontrivial boundary conditions are imposed on the extra S2/Z2 space.

Realization of a spontaneous gauge and supersymmetry breaking vacuum [PDF]
Journal of High Energy Physics, 2017 It is one of the major issues to realize a vacuum which breaks supersymmetry (SUSY) and R-symmetry, in a supersymmetric model. We study the model, where the same sector breaks the gauge symmetry and SUSY. In general, the SUSY breaking model without gauge

A note on unfree gauge symmetry [PDF]
Nuclear Physics B, 2019 We study the general structure of field theories with the unfree gauge symmetry where the gauge parameters are restricted by differential equations.

Symmetry-enriched quantum spin liquids in (3 + 1)d [PDF]
Journal of High Energy Physics, 2020 We use the intrinsic one-form and two-form global symmetries of (3+1)d bosonic field theories to classify quantum phases enriched by ordinary (0-form) global symmetry. Different symmetry-enriched phases correspond to different ways of coupling the theory

Non-invertible symmetries from discrete gauging and completeness of the spectrum [PDF]
Journal of High Energy Physics, 2023 We study global 1- and (d − 2)-form symmetries for gauge theories based on disconnected gauge groups which include charge conjugation. For pure gauge theories, the 1-form symmetries are shown to be non-invertible.

Gauge symmetry breaking in gauge theories---In search of clarification [PDF]
arXiv, 2011 The paper investigates the spontaneous breaking of gauge symmetries in gauge theories from a philosophical angle, taking into account the fact that the notion of a spontaneously broken local gauge symmetry, though widely employed in textbook expositions of the Higgs mechanism, is not supported by our leading theoretical frameworks of gauge quantum ...

The standard model gauge symmetry from higher-rank unified groups in grand gauge-Higgs unification models [PDF]
Journal of High Energy Physics, 2017 We study grand unified models in the five-dimensional space-time where the extra dimension is compactified on S 1/ℤ 2. The spontaneous breaking of unified gauge symmetries is achieved via vacuum expectation values of the extra-dimensional components of ...

Gauge symmetries of the teleparallel theory of gravity [PDF]
Class.Quant.Grav. 17 (2000) 3785-3798, 2000 We study gauge properties of the general teleparallel theory of gravity, defined in the framework of Poincare gauge theory. It is found that the general theory is characterized by two kinds of gauge symmetries: a specific gauge symmetry that acts on Lagrange multipliers, and the standard Poincare gauge symmetry.
