(Pseudo)goldstinos, SUSY fluids, Dirac gravitino and gauginos

Understand

We review the emergence and fate of goldstinos in different frameworks.

• First, we consider a super-Higgs mechanism when supersymmetry breaking is induced by neither an F-term nor a D-term but related to a more general stress energy-momentum tensor.
• This allows us to build a novel Lagrangian that describes the propagation of a spin-3/2 state in a fluid.
• Then we briefly review the ubiquitous pseudo-goldstinos when breaking supersymmetry in an extra dimension.
