Description
Even though there exists cosmological evidence of dark matter (DM) its terrestrial signal has not been observed yet. With no concrete hints of DM from any high energy physics experiment, a bottom-up approach is needed in the analysis of direct detection data. Specifically, the DAMA modulation effect provides a useful benchmark to test such strategies. For instance, we show that analyzing the data in terms of the most general non-relativistic Galilean invariant WIMP-nucleon interaction and/or following a halo-independent approach opens up new possibilities. In particular, we show that the WIMP scenario of proton-philic spin-dependent inelastic Dark Matter (pSIDM) can still provide a viable explanation of the observed DAMA effect in compliance with the constraints from other experiments. We also show that, although the COSINE-100 collaboration has recently tested the DAMA effect using the same target material, for the time being, the comparison between DAMA and COSINE-100 still depends on the particle–physics model.
