| Jan 3, 2018 at 21:22 | comment | added | Frederic Thomas | I think, it has use. Imagine the large number of physicists desperately searching for physics beyond the SM, in particular for its supersymmetric extension. Any sign in that sense would be a large encouragement. What if dark matter consists mainly of gravitinos ? | |

| Dec 12, 2017 at 15:31 | comment | added | DanielC | Field equations have relevance in classical physics. Supersymmetry and supergravity are thought as quantum theories, so any predictions of these two theories must be quantum. Any experiment could first tell us something about the quantum theory first and then, theoretically, also about the (semi)classical theory and its field equations. More precisely, let us say there is no experimental trace of the gravitino, then a quantum theory of the R-S field in the presence of the quantized gravitational field would be incorrect. You could infer that the E-H field equations of classical GR modified by | |
| Dec 12, 2017 at 14:32 | comment | added | Frederic Thomas | Thank you for the answer. I already read such kind of articles (above all from Samtleben) in vielbein-formalism. My question actually aims more at the physics than the purely necessary mathematics with all its requirements. Are possible modifications -- even in the necessary mathematical formalism -- of the field equations measurable ? | |
