witam cosmo-torun,

The DAMA detections of nbDM seem to be getting even stronger!

Bernabei et al. ArXiv:0804.2741 now have their annual modulation
signal of non-baryonic dark matter from the Galactic DM Halo detected
"at 8.2 sigma CL": DAMA/NaI + DAMA/LIBRA.  Figures 2, 4 and 8 are
especially impressive.

Savage et al. have a nice article ArXiv:0808.3607 showing the regions
of parameter space for WIMPS for which are consistent with both the
DAMA detection and all the non-detections in other experiments.
E.g. spin-dependent, proton-only couplings for a particle mass of
about 5-9 GeV are one region compatible with all the data.

This doesn't stop LDM (light dark matter) *also* being a correct
hypothesis for nbDM - multiple DM particles may contribute together to
non-baryonic DM.
