A theory of dark matter

We propose a comprehensive theory of dark matter that explains the recent proliferation of unexpected observations in high-energy astrophysics. Cosmic ray spectra from ATIC and PAMELA require a WIMP (weakly interacting massive particle). with mass ${M}_{\ensuremath{\chi}}\ensuremath{\sim}500--800\text{ }\text{ }\mathrm{GeV}$ that annihilates into leptons at a level well above that expected from a thermal relic. Signals from WMAP and EGRET reinforce this interpretation. Limits on $\overline{p}$ and ${\ensuremath{\pi}}^{0}\mathrm{\text{\ensuremath{-}}}\ensuremath{\gamma}$'s constrain the hadronic channels allowed for dark matter. Taken together, we argue these facts imply the presence of a new force in the dark…
