A theory of dark matter
� > 1GeV 1 . The long range allows a Sommerfeld enhancement to boost the annihilation cross section as required, without altering the weak-scale annihilation cross section during dark matterExpand
Inelastic dark matter
Many observations suggest that much of the matter of the universe is nonbaryonic. Recently, the DAMA NaI dark matter direct detection experiment reported an annual modulation in their event rateExpand
Flavor in Supersymmetry with an Extended R-symmetry
We propose a new solution to the supersymmetric flavor problem without flavor-blind mediation. Our proposal is to enforce a continuous or a suitably large discrete R-symmetry on weak scaleExpand
Dirac gaugino masses and supersoft supersymmetry breaking
We introduce a new supersymmetric extension of the standard model in which the gauge sector contains complete N = 2 supersymmetry multiplets. Supersymmetry breaking from the D-term vev of a hiddenExpand
The Fermi Haze: A Gamma-Ray Counterpart to the Microwave Haze
The Fermi Gamma-ray Space Telescope reveals a diffuse inverse Compton (IC) signal in the inner Galaxy with a similar spatial morphology to the microwave haze observed by WMAP, supporting theExpand
Cores in dwarf galaxies from dark matter with a Yukawa potential.
We show that cold dark matter particles interacting through a Yukawa potential could naturally explain the recently observed cores in dwarf galaxies without affecting the dynamics of objects with aExpand
Small Neutrino Masses from Supersymmetry Breaking
An alternative to the conventional see-saw mechanism is proposed to explain the origin of small neutrino masses in supersymmetric theories. The masses and couplings of the right-handed neutrino fieldExpand
Dark energy from mass varying neutrinos
We show that mass varying neutrinos (MaVaNs) can behave as a negative pressure fluid which could be the origin of the cosmic acceleration. We derive a model independent relation between the neutrinoExpand
Exciting dark matter and the INTEGRAL/SPI 511 keV signal
We propose a dark matter candidate with an 'excited state' 1-2 MeV above the ground state, which may be collisionally excited and deexcites by e{sup +}e{sup -} pair emission. By converting itsExpand
Simplified Models for Dark Matter Searches at the LHC
This document outlines a set of simplified models for dark matter and its interactions with Standard Model particles. It is intended to summarize the main characteristics that these simplified modelsExpand
