Accidental stability of dark matter    [PDF]

L. Lavoura, S. Morisi, J. W. F. Valle

We propose that dark matter is stable as a consequence of an accidental Z2 that results from a flavour-symmetry group which is the double-cover group of the symmetry group of one of the regular geometric solids. Although model-dependent, the phenomenology resembles that of a generic Higgs portal dark matter scheme.
