Leptophilic Dark Matter
Patrick J. Fox, Erich Poppitz

TL;DR
This paper proposes a simple leptophilic dark matter model with a broken U(1) gauge symmetry that explains cosmic ray excesses and DAMA signals while satisfying existing constraints.
Contribution
It introduces a novel dark sector model featuring a broken U(1) gauge symmetry that couples only to leptons and dark matter, explaining multiple experimental signals.
Findings
Explains PAMELA/ATIC cosmic ray excesses.
Accounts for DAMA annual modulation signal.
Consistent with current experimental constraints.
Abstract
We describe a simple model of Dark Matter, which explains the PAMELA/ATIC excesses while being consistent with all present constraints. The DAMA annual modulation signal can also be explained for some values of the parameters. The model consists of a Dark Sector containing a weakly coupled broken U(1) gauge symmetry, under which only the Dark Matter state and the leptons are charged.
