The lightest neutral scalar of the SU(2)_R triplet in the minimal left-right model can serve as a long-lived decaying dark matter candidate in the keV to multi-MeV mass range, provided the left-right scale exceeds about 10^15 GeV via a severely fine-tuned quartic coupling.

Decaying scalar dark matter in the minimal left-right symmetric model
The lightest neutral scalar of the SU(2)_R triplet in the minimal left-right model can serve as a long-lived decaying dark matter candidate in the keV to multi-MeV mass range, provided the left-right scale exceeds about 10^15 GeV via a severely fine-tuned quartic coupling.
