DeepCore - Extending the physics reach of the IceCube Neutrino Observatory
Date: Thursday, April 15th
Time: 4:00 pm
Place: 4274 Chamberlin
Speaker: Darren Grant, University of Alberta
Abstract: IceCube's DeepCore is a compact Cherenkov detector located at the bottom-centre of the neutrino observatory. It's purpose is to enhance the sensitivity of IceCube to low neutrino energies (< ~300GeV) and lower the detection threshold of the observatory by an order of magnitude to ~10 GeV. The improved sensitivity in this low-energy window enhances the ability of the observatory to perform dark matter searches via the products of WIMP annihilations, and thus probe an extensive range of the allowable SUSY parameter space for spin-dependent interactions. It also opens new possibilities for atmospheric neutrino oscillation measurements, muon neutrino disappearance and tau neutrino appearance, in an energy region not well tested by previous experiments. Finally, utilizing the IceCube array as an active veto, DeepCore enlarges the field of view of the observatory to the full sky when searching for potential neutrino sources. In this talk I will discuss the current status of the detector, fully deployed as of January 2010, and the development of the DeepCore analyses.
