Description

The main strategy of dark matter (DM) direct searches is to look for nuclear recoils from DM particles scattering on the detector medium. Of all the existing DM direct detection experiments only the DAMA experiment claims to observe the characteristic annually oscillating DM signal with the right phase at the significance level of ~ 12 sigma. Since many other experiments using various methods and having, in principle, better sensitivity to nuclear recoils detect nothing and put severe constraints on the DM mass and cross section, the conventional interpretation of the DAMA results, i.e. weakly interacting DM scattering on nuclei, becomes questionable. One of the possible explanations is related to the model of DM which interacts strongly with the ordinary matter. Given some assumptions about the peculiar features of DM interaction one can expect the signal in DAMA and the absence of any signal in other existing detectors. I am going to show why such kind of models fails to reproduce the DAMA signal.
