New Directions in Direct Dark Matter Searches

الملخص EN

I present the status of direct dark matter detection with specific attention to the experimental results and their phenomenological interpretation in terms of dark matter interactions.

In particular I review a new and more general approach to study signals in this field based on nonrelativistic operators which parametrize more efficiently the dark matter-nucleus interactions in terms of a very limited number of relevant degrees of freedom.

Then I list the major experimental results, pointing out the main uncertainties that affect the theoretical interpretation of the data.

Finally, since the underlying theory that describes both the dark matter and the standard model fields is unknown, I address the uncertainties coming from the nature of the interaction.

In particular, the phenomenology of a class of models in which the interaction between dark matter particles and target nuclei is of a long range type is discussed.
