Query: Double Higgs mechanisms, supermassive stable particles and the vacuum
  energy   In the present work it is shown that some specific double Higgs like
mechanisms may have interesting cosmological applications. A hidden scenario
which cast long lived super heavy particles together with an extremely light
particle $a$ with mass $m_a\sim 10^{-32}-10^{-33}$eV is presented. The
potential energy of this particle models the vacuum energy density of the
universe $\rho_c\simeq 10^{-47}\;\hbox{GeV}^4$. The construction of such
scenario is non trivial since the presence of light particles may spoil the
stability of the heavy particles. However, double Higgs mechanisms may be
helpful for overcoming this problem. The hidden sector we propose include
fermions with masses near the neutrino mass $m_\nu\sim 10^{-2}$eV which arise
in terms of a see saw mechanism. Besides, the super heavy particles acquire a
mass due to a double Higgs like mechanism of the order of the GUT scale. The
gauge group of the model is $\hbox{SU(2)}_L$ and the scalars of the double
Higgs mechanism are not charged under these interactions. The light particle
$a$ is the Goldstone boson associated to a Peccei-Quinn like symmetry in the
double Higgs model. In addition, the double Higgs mechanism posses another CP
odd scalar $A^0$, which acquire a mass of the order of the GUT scale. We show
that if there is no direct coupling between $A^0$ and $a$, even in presence of
indirect couplings, the $A^0$ particle is long lived an may appear in events
above the GKZ bound in present times.
