Particle Physics Seminar
"A Walk on the Dark Side"
Presented by Cristiano Galbiati, Princeton University

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 â€œdark matterâ€ 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 â€œdark matter puzzleâ€ 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.
