Positron Excess, Luminous-Dark Matter Unification and Family Structure
  It is commonly assumed that dark matter may be composed of one or at most a
few elementary particles. PAMELA data present a window of opportunity into a
possible relationship between luminous and dark matter. Along with ATIC data
the two positron excesses are interpreted as a reflection of dark matter family
structure. In a unified model it is predicted that at least a third enhancement
might show up at a different energy. The strength of the enhancements however
depends on interfamily mixing angles.
