Description
Detection of a Dark Matter signal in an ultra-low background terrestrial detector will provide the most direct evidence of its existence and will represent a ground-breaking discovery in physics and cosmology. Among the variety of dark matter detectors, liquid xenon time projection chambers have shown to be the most sensitive, thanks to a combination of very large target mass, ultra-low background and excellent signal-to-noise discrimination. Experiments based on this technology have led the field for the past decade. I will review the world leading results achieved with the first tonne scale experiment, XENON1T, before discussing sensitivity and discovery potential of the larger XENONnT and LZ expected to become operational this year.
