Superheavy dark matter from string theory

A bstract Explicit string models which can realize inflation and low-energy supersymmetry are notoriously difficult to achieve. Given that sequestering requires very specific configurations, supersymmetric particles in general expected be heavy implying the neutralino dark matter should overproduced a standard thermal history. However, this paper we point out is generically not case since early domination driven by moduli dilute abundance down observed value. We argue generic features of compactifications, namely high breaking scale late time epochs modulus domination, might imply superheavy with mass around 10 –10 11 GeV. Interestingly, right range explain recent detection ultra-high-energy neutrinos IceCube ANITA via decay.
