| Abstract: | There is a wide range of astronomical evidence that the visible stars and gas in all galaxies, including our own, are immersed in a much larger cloud of non-luminous matter, typically an order of magnitude greater in total mass. The existence of this “dark matter” is consistent with evidence from large-scale galaxy surveys and microwave background measurements, indicating that the majority of matter in the universe is non-baryonic. The nature of this non-baryonic component is still totally unknown, and the resolution of the “dark matter puzzle” is of fundamental importance to cosmology, astrophysics, and elementary particle physics. Three major lines of research are directing their efforts at detection of dark matter: the accelerator-based program at the LHC, indirect searches with satellite-born detectors and direct searches with detectors operated in deep underground laboratories. The time is ripe for a discovery, and the new generation of direct searches promises to probe the most interesting region of parameters for the dark matter candidates. I will review and describe the DarkSide underground argon detector at LNGS. |
| Speaker: | Cristiano Galbiati - Princeton University
 Professor Galbiati earned his PhD from the University of Milano, Italy, in 1999, working on the Borexino neutrino experiment at Gran Sasso. He spent a year in the Italian Navy before taking a postdoc at Princeton, where he has been ever since. In addition to continuing work with the Borexino collaboration, he has pursued the direct detection of dark matter with the WARP, MAX and Darkside collaborations. He will describe the Darkside detector at LNGS
