Positron Excess, Luminous-Dark Matter Unification and Family Structure

TL;DR

This paper proposes a unified model linking luminous and dark matter, interpreting positron excesses as evidence of dark matter family structure, and predicts additional signals depending on interfamily mixing.

Contribution

It introduces a novel unified framework connecting dark and luminous matter and predicts new observable features in positron data based on dark matter family structure.

Findings

Positron excesses suggest dark matter family structure.

A third enhancement is predicted at a different energy.

Enhancement strengths depend on interfamily mixing angles.

Abstract

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.
