The tiny order of magnitude of the cosmological constant is sought to be explained in a model involving the following ingredients: supersymmetry breaking in N=1 supergravity and the multiple point principle. We demonstrate the viability of this scenario in the minimal SUGRA model.

Predicting the SUSY breaking scale in SUGRA models with degenerate vacua
hep-ph 2019-09 conditional novelty 5.0 of 10

Assuming exactly degenerate supergravity vacua and two-loop running, the measured cosmological constant is matched only when the SUSY breaking scale is between 20 and 400 TeV.
