Compactifying de Sitter Naturally Selects a Small Cosmological Constant

arXiv:1311.2586 · doi:10.1103/PhysRevD.90.124048

Abstract

We study compactifications of $D$ -dimensional de Sitter space with a $q$ -form flux down to $D - N q$ dimensions. We show that for $(N - 1) (q - 1) \geq 2$ there are double-exponentially or even infinitely many compact de Sitter vacua, and that their effective cosmological constants accumulate at zero. This population explosion of $I^ ≪ 1$ de Sitters arises by a mechanism analogous to natural selection.
