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 ...

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 ...

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.

Spontaneous breaking of gauge groups to discrete symmetries [PDF]

Journal of High Energy Physics, 2017
A bstractMany models of beyond Standard Model physics connect flavor symmetry with a discrete group. Having this symmetry arise spontaneously from a gauge theory maintains compatibility with quantum gravity and can be used to systematically prevent ...

Discrete gauge symmetries and the weak gravity conjecture [PDF]

Journal of High Energy Physics, 2019
In theories with discrete Abelian gauge groups, requiring that black holes be able to lose their charge as they evaporate leads to an upper bound on the product of a charged particle’s mass and the cutoff scale above which the effective description of ...

A SymTFT for continuous symmetries [PDF]

Journal of High Energy Physics
Symmetry is a powerful tool for studying dynamics in QFT: it provides selection rules, constrains RG flows, and often simplifies analysis. Currently, our understanding is that the most general form of symmetry is described by categorical symmetries which

Spinorial discrete symmetries and adjoint structures [PDF]

Physics Letters, 2022
Extending the investigations about the theory of duals, we analyze duals built up with the aid of discrete symmetry operators. We scrutinize algebraic and physical constraints (encompassing them in a theoretical scope) in order to verify which ...

Discrete symmetries, weak coupling conjecture and scale separation in AdS vacua [PDF]

Journal of High Energy Physics, 2020
We argue that in theories of quantum gravity with discrete gauge symmetries, e.g. Zk , the gauge couplings of U(1) gauge symmetries become weak in the limit of large k, as g → k−α with α a positive order 1 coefficient.
