SUPER-Screening

Brax, Philippe, Davis, Anne-Christine, Sakstein, Jeremy

Understand

We present a framework for embedding scalar-tensor models of screened modifed gravity such as chameleons, symmetrons and environmental dilatons into global supersymmetry.

  • This achieved by secluding the dark sector from both the observable and supersymmetry breaking sectors.
  • We examine the resulting supersymmetric features in a model-independent manner and find that, when the theory follows from an underlying supergravity, the mediation of supersymmetry breaking to the dark sector induces a soft mass for the scalar of order the gravitino mass.
  • This is enough to forbid the construction of supersymmetric symmetrons and ensures that when other screening mechanisms operate, no object in the universe is unscreened thereby precluding any observable signatures.
