The authors' main claim 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.

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.

In this paper, a scan over the parameter space for iDM is performed, where we marginalize over the dark matter parameters $(m, δ, σ)$ and halo velocity parameters $(v_0, v_esc, v⃗_stream)$, and set constraints by a global $χ^2$ analysis [ref] .[In some circumstances, maximum gap techniques provide tighter limits than Poisson statistics for null experiments [ref] .

A comparison with Fig. 7 of [ref] shows that the resulting cross section can still explain DAMA, whereas the analysis [ref] already excludes this cross section assuming a standard DM profile.

The idea that Dark Matter (DM) particles can only interact with Standard Model (SM) particles through an inelastic transition from a lighter to a heavier (excited) state was first proposed as a possible interpretation of the DAMA annual modulation signal [ref] consistent with null results from other direct detection experiments [ref] .
