Abstract: (arXiv)

We propose that the leptonic cosmic ray signals seen by PAMELA and ATIC result from the annihilation or decay of dark matter particles via states of a leptonic Higgs doublet to

\tau

leptons, linking cosmic ray signals of dark matter to LHC signals of the Higgs sector. The states of the leptonic Higgs doublet are lighter than about 200 GeV, yielding large

\bar{\tau} \tau

and

\bar{\tau} \tau \bar{\tau} \tau

event rates at the LHC. Simple models are given for the dark matter particle and its interactions with the leptonic Higgs, for cosmic ray signals arising from both annihilations and decays in the galactic halo. For the case of annihilations, cosmic photon and neutrino signals are on the verge of discovery.

dark matter: annihilation
dark matter: decay
lepton: emission
lepton: cosmic radiation
photon: cosmic radiation
neutrino: cosmic radiation
