Description
Detectors using liquid noble gas media like xenon or argon have shown a great potential for direct dark matter searches. Particles interacting with these targets cause the emission of light and free electrons, via excitation and ionization processes, respectively.
The pulse shape of the prompt light signal and/or the ratio between light and extracted charge can be used to discriminate between different types of particles. For instance, nuclear recoils from dark
matter interactions can be separated from electronic recoils from natural radioactivity, the main background contribution for this kind of experiments.
In this talk talk the different working principles of liquid noble-gas detectors are summarized. Furthermore, an overview of current and future experiments using the liquid noble gas technology is given, including the most important physics results and prospectives.
