@article{Roest2017InternalSA, title={Internal supersymmetry and small-field Goldstini}, author={D. van der Roest and Pelle Werkman and Yusuke Yamada}, journal={Journal of High Energy Physics}, year={2017}, volume={2018}, pages={1-12} }

A bstractThe 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 limit of this theory. This model non-linearly realizes an alternative supersymmetry algebra with vanishing anti-commutators between the fermionic generators, much like an internal supersymmetry. This Goldstino theory is akin to the Galilean scalar field theory that arises as the small-field limit of Dirac…
