Improved Constraints on Inelastic Dark Matter
  We perform an extensive study of the DAMA annual modulation data in the
context of inelastic dark matter. We find that inelastic dark matter with mass
m > 15 GeV is excluded at the 95% confidence level by the combination of DAMA
spectral information and results from other direct detection experiments.
However, at smaller m, inelastic dark matter constitutes a possible solution to
the DAMA puzzle.
