Flavored Dark Matter and the Galactic Center Gamma-Ray Excess
  Thermal relic dark matter particles with a mass of 31-40 GeV and that
dominantly annihilate to bottom quarks have been shown to provide an excellent
description of the excess gamma rays observed from the center of the Milky Way.
Flavored dark matter provides a well-motivated framework in which the dark
matter can dominantly couple to bottom quarks in a flavor-safe manner. We
propose a phenomenologically viable model of bottom flavored dark matter that
can account for the spectral shape and normalization of the gamma-ray excess
while naturally suppressing the elastic scattering cross sections probed by
direct detection experiments. This model will be definitively tested with
increased exposure at LUX and with data from the upcoming high-energy run of
the Large Hadron Collider (LHC).
