Title: Dark matter searches in liquid Xenon Speaker: Alex Kish, UZH Abstract: In our present understanding, most of the matter in the Universe is in a form of dark matter (non-baryonic and non-luminous), with the best motivated candidate being a Weakly Interacting Massive Particle (WIMP). Direct WIMPs detection is possible via their interactions with nuclei in low background terrestrial targets. A very efficient and promising technology which leads the active field of dark matter searches is detectors based on noble liquids, in particular xenon. They are relatively inexpensive, provide easy scalability, require relatively simple cryogenic systems, and have high scintillation and charge yields, which allows background discrimination with high efficiency. In the talk I will briefly give the evidence for dark matter from existing observations, introduce direct WIMP detection field, describe the principles of particle detection with the xenon-based detectors, and summarize my 8-years experience within the XENON project. The technological advances and results of the XENON100 experiment will be discussed, as well as the progress on the ongoing construction of the XENON1T detector at LNGS. An outlook into the ultimate multi-ton scale xenon-based experiment (DARWIN) will be also given.
