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

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.

Geometric phases for mixed states and decoherence [PDF]

, 2006
The gauge invariance of geometric phases for mixed states is analyzed by using the hidden local gauge symmetry which arises from the arbitrariness of the choice of the basis set defining the coordinates in the functional space.

BRST Symmetric Formulation of a Theory with Gribov-type Copies [PDF]

, 1995
A path integral with BRST symmetry can be formulated by summing the Gribov-type copies in a very specific way if the functional correspondence between $\tau$ and the gauge parameter $\omega$ defined by $\tau (x) = f( A_{\mu}^{\omega})$ is ``globally ...

Two Types of Jets and Quark and Chromon Model in QCD

Universe, 2019
We discuss the importance of the color reflection symmetry of the Abelian decomposition in QCD. The Abelian decomposition breaks up the color gauge field to three parts, the neuron, chromon, and the topological monopole, gauge independently. Moreover, it

Higher-form symmetries of 6d and 5d theories

Journal of High Energy Physics, 2021
We describe general methods for determining higher-form symmetry groups of known 5d and 6d superconformal field theories (SCFTs), and 6d little string theories (LSTs).

Symmetries in Constrained Systems [PDF]

, 2004
We describe symmetry structure of a general singular theory (theory with constraints in the Hamiltonian formulation), and, in particular, we relate the structure of gauge transformations with the constraint structure.

String Dualities in the Presence of Anomalous U(1) Symmetries [PDF]

, 1999
Anomalous U(1) gauge symmetries in type II orientifold theories show some unexpected properties. In contrast to the heterotic case, the masses of the gauge bosons are in general of order of the string scale even in the absence of large Fayet-Iliopoulos ...

Many-body Majorana-like zero modes without gauge symmetry breaking

Physical Review Research, 2021
Topological superconductors represent one of the key hosts of Majorana-based topological quantum computing. Typical scenarios for one-dimensional (1D) topological superconductivity assume a broken gauge symmetry associated to a superconducting state ...

(p − 1)-bracket for Dp-branes in large R-R field background

Journal of High Energy Physics, 2023
The volume-preserving diffeomorphism is a key feature that characterizes the large constant R-R (p − 1)-form field background in a Dp-brane theory. It represents a symmetry of the theory that preserves the volume of space.

Probing F-theory With Branes [PDF]

, 1996
Last week, A. Sen found an explicit type I string compactification dual to the eight-dimensional F-theory construction with SO(8)^4 nonabelian gauge symmetry.
