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.

Gauge symmetry from decoupling
Nuclear 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.

Mirror Symmetry as a Gauge Symmetry [PDF]
, 1994 It is shown that in string theory mirror duality is a gauge symmetry (a Weyl transformation) in the moduli space of $N=2$ backgrounds on group manifolds, and we conjecture on the possible generalization to other backgrounds, such as Calabi-Yau manifolds ...

Flexural Behavior of Bidirectionally Graded Lattice
Advanced Engineering Materials, EarlyView., 2023 An experimental study of the bending behavior of bidirectional body‐centered cubic lattice beams is conducted in comparison to uniform and unidirectional counterparts of electron beam melted SS 316 L. Experimental results are used to develop and validate a finite element model which is subsequently used to conduct parametric studies to assess the ...

(Non-)Aligned gauges and global gauge symmetry breaking [PDF]
Mod. Phys. Lett. A, Vol. 27, No. 38 (2012) 1250222, 2012 The concept of (global) gauge symmetry breaking plays an important role in many areas of physics. Since the corresponding symmetry is a gauge symmetry, its breaking is actually gauge-dependent. Thus, it is possible to design gauges which restore the symmetry as good as possible.

Disconnected 0-Form and 2-Group Symmetries [PDF]
, 2022 Quantum field theories can have both continuous and finite 0-form symmetries. We study global symmetry structures that arise when both kinds of 0-form symmetries are present. The global structure associated to continuous 0-form symmetries is described by a connected Lie group, which captures the possible backgrounds of the continuous 0-form symmetries ...

The `BRST-invariant' Condensate of Dimension Two in QCD [PDF]
, 2003 The status of the `BRST-invariant' condensate of mass dimension two in QCD is explained. The condensate is only invariant under an `on-shell' BRST symmetry which includes a partial gauge-fixing.

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

Confinement transition of ℤ2 gauge theories coupled to massless fermions: Emergent quantum chromodynamics and SO(5) symmetry [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Universal properties of quantum (zero-temperature) phase transitions are typically well-described by the classical Landau theory of spontaneous symmetry breaking.
