Categorisation and Detection of Dark Matter Candidates from String/M-theory Hidden Sectors

Understand

We study well-motivated dark matter candidates arising from weakly-coupled hidden sectors in compactified string/$M$-theory.

• Imposing generic top-down constraints greatly restricts allowed candidates.
• By considering the possible mechanisms for achieving the correct dark matter relic density, we compile categories of viable dark matter candidates and annihilation mediators.
• We consider the case where supersymmetry breaking occurs via moduli stabilisation and is gravitationally mediated to the visible and other hidden sectors, without assuming sequestering of the sector in which supersymmetry is broken.
