Description
The fundamental nature of dark or invisible matter remains
one of the great mysteries of our time. A leading hypothesis is that dark matter is
made of new elementary particles, with proposed masses and interaction cross
sections spanning an enormous range. Amongst the technologies developed to
search for dark matter particles, two-phase (liquid and gas) xenon time projection
chambers are currently leading the field, providing unprecedented sensitivities and
a large discovery potential. I will briefly present the development of these detectors
from their earliest stages, then show first results from multi-tonne detectors
currently taking data deep underground. I will also discuss the ongoing the R&D;
towards the next-generation DARWIN experiment.
