Smallness of the cosmological constant and the multiple point principle
Smallness of the cosmological constant and the multiple point principle
In this talk we argue that the breakdown of global symmetries in no-scale supergravity (SUGRA), which ensures the vanishing of the vacuum energy density near the physical vacuum, leads to a natural realisation of the multiple point principle (MPP). In the MPP inspired SUGRA models the cosmological constant is naturally …
