Explaining B →K (*) ℓ + ℓ - anomaly by radiatively induced coupling in U (1 ) μ -τ gauge symmetry [PDF]
, 2017 We propose an extension of the standard model (SM) with $U(1)_{\mu-\tau}$ gauge symmetry, extra vectorlike quark doublets $Q'_a$ and singlet scalar $\chi$, both of which are charged under $U(1)_{\mu-\tau}$ and carry {odd} dark $Z_2$ parity. Then assuming

Multicomponent Dark Matter from gauge symmetry [PDF]
Journal of High Energy Physics, 2016 The composition of Dark Matter (DM) remains an important open question. The current data do not distinguish between single- and multi-component DM, while in theory constructions it is often assumed that DM is composed of a single field.

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.

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.

Gauge Freedom in Path Integrals in Abelian Gauge Theory
, 2015 We extend gauge symmetry of Abelian gauge field to incorporate quantum gauge degrees of freedom. We twice apply the Harada--Tsutsui gauge recovery procedure to gauge-fixed theories.

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 ...

When ℤ2 one-form symmetry leads to non-invertible axial symmetries
Journal of High Energy Physics, 2023 We study non-abelian gauge theories with fermions in a representation such that the surviving electric 1-form symmetry is ℤ2. This includes SU(N) gauge theories with matter in the (anti)symmetric and N even, and USp(2N) with a Weyl fermion in the adjoint,

Hidden Gauge Symmetries: A New Possibility at the Colliders
, 2005 We consider a new physics possibility at the colliders: the observation of TeV scale massive vector bosons in the non-adjoint representations under the Standard Model (SM) gauge symmetry. To have a unitary and renormalizable theory, we propose a class of

Gauge theories on the noncommutative sphere [PDF]
, 1997 Gauge theories are formulated on the noncommutative two-sphere. These theories have only finite number of degrees of freedom, nevertheless they exhibit both the gauge symmetry and the SU(2) "Poincar\'e" symmetry of the sphere. In particular, the coupling
