Rare Event Searches underground: New physics opportunities and old claims

A diversification of the physics output in many existing rare event searches is possible. In this talk I will present theoretical scenarios of the hidden sector with an emphasis of their test in direct detection and neutrino experiments. I will show how DM multiplets can be probed in searches for the neutrinoless double beta decay and how, in turn, new forces in the neutrino sector can be tested in DM experiments. In a second part of the talk, the DAMA claim for a positive detection of Dark Matter in the laboratory will be scrutinized and comments on recent arXiv activity will be offered.
