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.…
Internal Supersymmetry and Small-field Goldstini
Diederik Roest, Pelle Werkman, Yusuke Yamada
The dynamics of the Goldstino mode of spontaneously broken supersymmetry is universal, being fully determined by the non-linearly realized symmetry. We investigate the small-field…
Moduli Backreaction on Inflationary Attractors
Diederik Roest, Marco Scalisi, Pelle Werkman
We investigate the interplay between moduli dynamics and inflation, focusing on the KKLT-scenario and cosmological -attractors. General couplings between these sectors can induc…
