Linking entanglement and discrete anomaly
Journal of High Energy Physics, 2018 In 3d Chern-Simons theory, there is a discrete one-form symmetry, whose symmetry group is isomorphic to the center of the gauge group. We study the ‘t Hooft anomaly associated to this discrete one-form symmetry in theories with generic gauge groups, A, B,

Scotogenic A5 → A4 Dirac neutrinos with freeze-in dark matter
Physics Letters B, 2022 Radiative Dirac neutrino masses and their mixing are linked to dark matter through the non-Abelian discrete symmetry A5 of the 4-dimensional pentatope, softly broken to A4 of the 3-dimensional tetrahedron.

Accidental Peccei–Quinn symmetry from discrete flavour symmetry and Pati–Salam
Physics Letters B, 2018 We show how an accidental U(1) Peccei–Quinn (PQ) symmetry can arise from a discrete A4 family symmetry combined with a discrete flavour symmetry Z3×Z52, in a realistic Pati–Salam unified theory of flavour. Imposing only these discrete flavour symmetries,

Tri-bimaximal mixing, discrete family symmetries, and a conjecture connecting the quark and lepton mixing matrices [PDF]
, 2003 Neutrino oscillation experiments (excluding the LSND experiment) suggest a tri-bimaximal form for the lepton mixing matrix. This form indicates that the mixing matrix is probably independent of the lepton masses, and suggests the action of an underlying ...

Dai-Freed anomaly in the standard model and topological inflation
Journal of High Energy Physics, 2023 When we impose discrete symmetries in the standard model we have Dai-Freed global anomalies. However, interestingly if we introduce three right-handed neutrinos we can have an anomaly-free discrete Z 4 gauge symmetry.

Invariants of Broken Discrete Symmetries [PDF]
Physical Review Letters, 2014 The parity and Bloch theorems are generalized to the case of broken global symmetry. Local inversion or translation symmetries are shown to yield invariant currents that characterize wave propagation. These currents map the wave function from an arbitrary spatial domain to any symmetry-related domain.

Discrete R symmetries and anomalies [PDF]
Journal of High Energy Physics, 2014 We comment on aspects of discrete anomaly conditions focussing particularly on $R$ symmetries. We review the Green-Schwarz cancellation of discrete anomalies, providing a heuristic explanation why, in the heterotic string, only the "model-independent dilaton" transforms non-linearly under discrete symmetries; this argument suggests that, in other ...

Anomalous discrete flavor symmetry and domain wall problem
Physics Letters B, 2019 Discrete flavor symmetry is often introduced for explaining quark/lepton masses and mixings. However, its spontaneous breaking leads to the appearance of domain walls, which is problematic for cosmology. We consider a possibility that the discrete flavor
