Carroll contractions of Lorentz-invariant theories [PDF]
Journal of High Energy Physics, 2021 We consider Carroll-invariant limits of Lorentz-invariant field theories. We show that just as in the case of electromagnetism, there are two inequivalent limits, one “electric” and the other “magnetic”.

Classical gravitational scattering from a gauge-invariant double copy [PDF]
Journal of High Energy Physics, 2021 We propose a method to compute the scattering angle for classical black hole scattering directly from two massive particle irreducible diagrams in a heavy-mass effective field theory approach to general relativity, without the need of subtracting ...

Towards critical physics in 2+1d with U(2N )-invariant fermions [PDF]
Journal of High Energy Physics, 2016 Interacting theories of N relativistic fermion flavors in reducible spinor representations in 2+1 spacetime dimensions are formulated on a lattice using domain wall fermions (DWF), for which a U(2N ) global symmetry is recovered in the limit that the ...

Modular invariant dynamics and fermion mass hierarchies around τ = i [PDF]
Journal of High Energy Physics, 2021 We discuss fermion mass hierarchies within modular invariant flavour models. We analyse the neighbourhood of the self-dual point τ = i, where modular invariant theories possess a residual Z4 invariance.

Explainable equivariant neural networks for particle physics: PELICAN [PDF]
Journal of High Energy Physics, 2023 PELICAN is a novel permutation equivariant and Lorentz invariant or covariant aggregator network designed to overcome common limitations found in architectures applied to particle physics problems.

The geometry of gauged (super)conformal mechanics
Journal of High Energy Physics, 2022 Motivated by recently explored examples, we undertake a systematic study of conformal invariance in one-dimensional sigma models where an isometry group has been gauged.

SYMMETRIES AND INVARIANCES IN CLASSICAL PHYSICS [PDF]
, 2007 This Chapter discusses the role of symmetry in classical physics. We begin, in Section 2, with the distinction between symmetries of objects and of laws, and that between symmetry principles and symmetry arguments, including a discussion of Curie’s principle.
