Conclusions Ø Non-relativistic effective models can fit the DAMA/LIBRA-phase 2 data with less fine tuning compared to a standard SI interaction (all model excluded by fluorine&xenon detectors) Ø WIMP-quark, WIMP-gluon interactions exclude upper bounds of DAMA Ø p. SIDM could explain DAMA/LIBRA-phase 1 in compliance with constraints from other experiments. Still OK after DAMA/LIBRA-phase 2 if WIMP velocity distribution departs from a Maxwellian. Ø In the non-relativistic effective theory parameter space, inelastic scattering partially relieves tension in sigmas between DAMA and other experiments.
