  To connect the scalar field (acceleron) responsible for dark energy to
neutrinos, the usual strategy is to add unnaturally light neutral singlet
fermions (right-handed neutrinos) to the Standard Model. A better choice is
actually a Higgs triplet, through the coupling of the acceleron to the
trilinear Higgs triplet-double-doublet interaction. This hypothesis predicts an
easily observable doubly-charged Higgs boson at the forthcoming Large Hadron
Collider (LHC).
