UV Constraints on Massive Spinning Particles: Lessons from the Gravitino
Scott Melville, Diederik Roest, David Stefanyszyn
Self-interacting massive particles with spin unavoidably violate unitarity; the question is at what scale. For spin- the strong coupling scale (at which perturbative un…
An Algebraic Classification of Exceptional EFTs Part II: Supersymmetry
Diederik Roest, David Stefanyszyn, Pelle Werkman
We present a novel approach to classify supersymmetric effective field theories (EFTs) whose scattering amplitudes exhibit enhanced soft limits. These enhancements arise due to non…
An Algebraic Classification of Exceptional EFTs
Diederik Roest, David Stefanyszyn, Pelle Werkman
We classify four-dimensional effective field theories (EFTs) with enhanced soft limits, which arise due to non-linearly realised symmetries on the Goldstone modes of such theories.…
