Deformed discrete symmetries [PDF]

Physics Letters B, 2016
We construct discrete symmetry transformations for deformed relativistic kinematics based on group valued momenta. We focus on the specific example of κ-deformations of the Poincaré algebra with associated momenta living on (a sub-manifold of) de Sitter ...

Hairs of discrete symmetries and gravity [PDF]

Physics Letters B, 2017
Gauge symmetries are known to be respected by gravity because gauge charges carry flux lines, but global charges do not carry flux lines and are not conserved by gravitational interaction.

Non-linearly realized discrete symmetries [PDF]

Journal of High Energy Physics, 2020
While non-linear realizations of continuous symmetries feature derivative interactions and have no potential, non-linear realizations of discrete symmetries feature non-derivative interactions and have a highly suppressed potential.

Discrete and higher-form symmetries in SCFTs from wrapped M5-branes [PDF]

Journal of High Energy Physics, 2021
We analyze topological mass terms of BF type arising in supersymmetric M-theory compactifications to AdS 5. These describe spontaneously broken higher-form gauge symmetries in the bulk. Different choices of boundary conditions for the BF terms yield dual

Discrete symmetries tested at 10^-4 precision using linear polarization of photons from positronium annihilations. [PDF]

Nat Commun
Discrete symmetries play an important role in particle physics with violation of CP connected to the matter-antimatter imbalance in the Universe. We report the most precise test of P, T and CP invariance in decays of ortho-positronium, performed with ...

Discrete Symmetries of Complete Intersection Calabi-Yau Manifolds [PDF]

Communications in Mathematical Physics, 2017
In this paper, we classify non-freely acting discrete symmetries of complete intersection Calabi- Yau manifolds and their quotients by freely-acting symmetries.

Discrete symmetries in dimer diagrams [PDF]

Journal of High Energy Physics, 2019
We apply dimer diagram techniques to uncover discrete global symmetries in the fields theories on D3-branes at singularities given by general orbifolds of general toric Calabi-Yau threefold singularities.

Discrete Lorentz symmetry and discrete time translational symmetry [PDF]

New Journal of Physics, 2018
The Lorentz symmetry and the space and time translational symmetry are fundamental symmetries of nature. Crystals are the manifestation of the continuous space translational symmetry being spontaneously broken into a discrete one.

Discrete theta angles, symmetries and anomalies [PDF]

SciPost Physics, 2021
Gauge theories in various dimensions often admit discrete theta angles, that arise from gauging a global symmetry with an additional symmetry protected topological (SPT) phase.

Discrete gauge groups in F-theory models on genus-one fibered Calabi-Yau 4-folds without section [PDF]

Journal of High Energy Physics, 2017
We determine the discrete gauge symmetries that arise in F-theory compactifications on examples of genus-one fibered Calabi-Yau 4-folds without a section.
