A common scenario for an small vacuum energy and long lived super heavy
dark matter    [PDF]

O. P. Santillan

A toy model originating super heavy dark matter and an small vacuum density
energy, of the order of the one measured in the present era is constructed.
This is obtained by considering a hidden sector with an axion like particle
associated to an extremely weak interaction together with a super massive Higgs
like boson. The axion acts as a false vacuum, and the hidden Higgs may be
created in the early universe. By employing a crude estimation we suggest that
the mean lifetime of this hidden Higgs is larger than the age of the universe.
We argue that this particle ac as a component of the dark matter at present
times. The approach to the vacuum energy problem presented here is a
quintessence like mechanism, in which it is assumed that the true vacuum
density energy is zero for some reason, except for the contribution of the
light axion.
