LHC Signals for a SuperUnified Theory of Dark Matter
Nima Arkani-Hamed, Neal Weiner
A new theory of WIMP Dark Matter has been proposed, motivated directly by striking Data from the PAMELA and ATIC collaborations. The WIMP is taken to be charged under a hidden gaug…
The Case for a 700+ GeV WIMP: Cosmic Ray Spectra from PAMELA, Fermi and ATIC
Ilias Cholis, Gregory Dobler, Douglas P. Finkbeiner +2
Multiple lines of evidence indicate an anomalous injection of high-energy e+- in the Galactic halo. The recent fraction spectrum from the Payload for Antimatter Matter Explor…
Nuclear scattering of dark matter coupled to a new light scalar
Douglas P. Finkbeiner, Tracy R. Slatyer, Neal Weiner
We consider the nuclear scattering cross section for the eXciting Dark Matter (XDM) model. In XDM, the Weakly Interacting Massive Particles (WIMPs) couple to the Standard Model onl…
A Theory of Dark Matter
Nima Arkani-Hamed, Douglas P. Finkbeiner, Tracy R. Slatyer +1
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 PAM…
High Energy Positrons From Annihilating Dark Matter
Ilias Cholis, Lisa Goodenough, Dan Hooper +2
Recent preliminary results from the PAMELA experiment indicate the presence of an excess of cosmic ray positrons above 10 GeV. In this letter, we consider possibility that this sig…
Using the Energy Spectrum at DAMA/LIBRA to Probe Light Dark Matter
Spencer Chang, Aaron Pierce, Neal Weiner
A weakly interacting massive particle (WIMP) weighing only a few GeV has been invoked as an explanation for the signal from the DAMA/LIBRA experiment. We show that the data from DA…
