Description
The Festina Lente (FL) bound arises from demanding that very large charged black holes in universes with a positive cosmological constant must decay without becoming singular. The FL bound states that the mass of all charged states is bounded from below by a scale set by the vacuum energy.
In this talk, I will first review the argument for the FL bound from charged black hole decay. I will discuss some of the pheno applications of the FL bound such as to the electroweak hierarchy problem and to Higgs physics. I will discuss the FL bound in a string theory context and go over what it implies for string compactifications with a positive cosmological constant generally and antibrane uplifts specifically.
