Directional Dark Matter Searches with Carbon Nanotubes
  A new solution to the problem of dark matter directional detection might come
from the use of large arrays of aligned carbon nanotubes. We calculate the
expected rate of carbon ions channeled in single-wall nanotubes once extracted
by the scattering with a massive dark matter particle. Depending on its initial
kinematic conditions, the ejected Carbon ion may be channeled in the nanotube
array or stop in the bulk. The orientation of the array with respect to the
direction of motion of the Sun has an appreciable effect on the channeling
probability. This provides the required anisotropic response for a directional
detector.
