Abstract

We study candidates for dark matter in a minimal flipped SU(5)×U(1) supersymmetric GUT. Since the model has no R-parity, spin- 1 2 supersymmetric partners of conventional particles mix with other neutral fermions including neutrinos, and can decay into them. The lightest particle which is predominantly a gaugino/higgsino mixture decays with a lifetime τ_χ∼1-10⁹ s. The model contains a scalar "flaton" field whose coherent oscillations decay before cosmological nucleosynthesis, and whose pseudoscalar partner contributes negligibly to Ω if it is light enough to survive to the present epoch. The fermionic "flatino" partner of the flaton has a lifetime τ_Φ∼10²⁸-10³⁴ yr and is a viable candidate for metastable dark matter with Ω≲1.
