Sterile neutrinos and global symmetries [PDF]
Physical Review D, 2005 We use an effective-field-theory approach to construct models with naturally light sterile neutrinos, due to either exact or accidental global symmetries. The most attractive models we find are based on gauge symmetries, either discrete or continuous. We give examples of simple models based on Z_N, U(1)', and SU(2)'.

Dyson’s classification and real division superalgebras
Journal of High Energy Physics, 2021 It is well-known that unitary irreducible representations of groups can be usefully classified in a 3-fold classification scheme: Real, Complex, Quaternionic.

Lifting M-theory to Two-Time Physics [PDF]
, 1999 M-theory has different global supersymmetry structures in its various dual incarnations, as characterized by the M-algebra in 11D, the type IIA, type-IIB, heterotic, type-I extended supersymmetries in 10D, and non-Abelian supersymmetries in the AdS_n x S^

Non-invertible symmetries from discrete gauging and completeness of the spectrum
Journal of High Energy Physics, 2023 We study global 1- and (d − 2)-form symmetries for gauge theories based on disconnected gauge groups which include charge conjugation. For pure gauge theories, the 1-form symmetries are shown to be non-invertible.

A particle model with extra dimensions from coadjoint Poincaré symmetry
Journal of High Energy Physics, 2020 Starting from the coadjoint Poincaré algebra we construct a point particle relativistic model with an interpretation in terms of extra-dimensional variables.

Non-invertible Gauss law and axions
Journal of High Energy Physics, 2023 In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries.

Global Anomalies in the Batalin Vilkovisky Quantization [PDF]
, 1996 The Batalin Vilkovisky (BV) quantization provides a general procedure for calculating anomalies associated to gauge symmetries. Recent results show that even higher loop order contributions can be calculated by introducing an appropriate regularization ...

Note on Discrete Gauge Anomalies
, 1991 We consider the probem of gauging discrete symmetries. All valid constraints on such symmetries can be understood in the low energy theory in terms of instantons.

Ghost Cohomologies and Hidden Space-Time Symmetries [PDF]
, 2007 We observe and study new non-linear global space-time symmetries of the full ghost+matter action of RNS superstring theory. We show that these surprising new symmetries are generated by the special worldsheet currents (vertex operators) of RNS ...

Mixed anomalies, two-groups, non-invertible symmetries, and 3d superconformal indices
Journal of High Energy Physics, 2023 Mixed anomalies, higher form symmetries, two-group symmetries and non-invertible symmetries have proved to be useful in providing non-trivial constraints on the dynamics of quantum field theories.
