Gauge Symmetries, Symmetry Breaking, and Gauge-Invariant Approaches

open access: yes, 2023
Gauge symmetries play a central role, both in the mathematical foundations as well as the conceptual construction of modern (particle) physics theories. However, it is yet unclear whether they form a necessary component of theories, or whether they can be eliminated. It is also unclear whether they are merely an auxiliary tool to simplify (and possibly

Realization of a spontaneous gauge and supersymmetry breaking vacuum

open access: yesJournal 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

Categorical symmetry and noninvertible anomaly in symmetry-breaking and topological phase transitions

open access: yesPhysical Review Research, 2020
For a zero-temperature Landau symmetry-breaking transition in n-dimensional space that completely breaks a finite symmetry G, the critical point at the transition has the symmetry G. In this paper, we show that the critical point also has a dual symmetry—

Localization of Gauge Theories on the Three-Sphere [PDF]

open access: yes, 2012
We describe the application of localization techniques to the path integral for supersymmetric gauge theories in three dimensions. The localization procedure reduces the computation of the expectation value of BPS observables to a calculation in a matrix

Gauge symmetry from decoupling

open access: yesNuclear Physics B, 2017
Gauge symmetries emerge from a redundant description of the effective action for light degrees of freedom after the decoupling of heavy modes. This redundant description avoids the use of explicit constraints in configuration space.

Gauge enhanced quantum criticality and time reversal deconfined domain wall: SU(2) Yang-Mills dynamics with topological terms

open access: yesPhysical Review Research, 2020
We explore the low-energy dynamics of the four siblings of Lorentz symmetry enriched SU(2) Yang-Mills theories with a theta term at θ=π in (3+1)d. Due to a mixed anomaly between time reversal symmetry and the one-form center symmetry, the low-energy ...

Gauge-Higgs Unification Models in Six Dimensions with S2/Z2 Extra Space and GUT Gauge Symmetry

open access: yesAdvances 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.

Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]

open access: yes, 2010
The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...

Instantons, symmetries and anomalies in five dimensions

open access: yesJournal of High Energy Physics, 2021
All five-dimensional non-abelian gauge theories have a U(1) I global symmetry associated with instantonic particles. We describe an obstruction to coupling U(1) I to a classical background gauge field that occurs whenever the theory has a one-form center

Dynamical Symmetry Breaking of Extended Gauge Symmetries [PDF]

open access: yesPhysical Review Letters, 2003
We construct asymptotically free gauge theories exhibiting dynamical breaking of the left-right, strong-electroweak gauge group $G_{LR} = {\rm SU}(3)_c \times {\rm SU}(2)_L \times {\rm SU}(2)_R \times {\rm U}(1)_{B-L}$, and its extension to the Pati-Salam gauge group $G_{422}={\rm SU}(4)_{PS} \times {\rm SU}(2)_L \times {\rm SU}(2)_R$.
