Title : Theoretical bounds on dark matter masses

Abstract : We show that quantum gravity leads to lower and upper bounds
on the masses of dark matter candidates. These bounds depend on the spins of
the dark matter candidates and the nature of interactions in the dark matter sector.
For example, for singlet scalar dark matter(phi), we find a mass range
10^(-3) eV <~ m_phi <~ 10^7 eV .
The lower bound comes from limits on fifth force type interactions and
the upper bound from the lifetime of the dark matter candidate.
