Stringy WIMP Detection and Annihilation
  We calculate the direct dark matter detection spin-independent and proton
spin-dependent cross-sections for a semi-realistic intersecting D6-brane model.
The cross-sections are compared to the latest constraints of the current dark
matter direct detection experiments, as well as the projected results of future
dark matter experiments. The allowed parameter space of the intersecting
D6-brane model is shown with all current experimental constraints, including
those regions satisfying the WMAP and Supercritical String Cosmology (SSC)
limits on the dark matter density in the universe. Additionally, we compute the
indirect detection gamma-ray flux resulting from neutralino annihilation for
the D6-brane model and compare the flux to the projected sensitivity of the
Fermi Gamma-ray Space Telescope. Finally, we compute the direct and indirect
detection cross-sections as well as the gamma-ray flux resulting from WIMP
annihilations for the one-parameter model for comparison, where the
one-parameter model is a highly constrained subset of the mSUGRA parameter
space such that the soft supersymmetry breaking terms are functions of the
common gaugino mass, which is common to many string compactifications.
