As the Deep Underground Science and Engineering Laboratory (DUSEL) moves into its next design phase, more experimental projects are actively evolving in their design, R&D, and experiment site planning in DUSEL. The workshop will bring together experimentalists and theorists who are working and seek to collaborate in DUSEL based experiments. Work by scientists in South Dakota will also be introduced.
Topics to be covered during the workshop include:
- Dark Matter
It is now almost universally recognized that approximately 20-25% of the universe's energy density resides in the form of dark matter particles, with WIMPs or weakly interacting massive particles the leading dark matter candidates. The Standard Model of high-energy physics offers no viable WIMP candidate. However, one of the leading WIMP candidates is the neutralino, the lightest supersymmetric particle. The 7-14 TeV energies available at the Large Hadron Collider (LHC) at CERN may turn out to be sufficient to produce WIMP particles directly. Underground experiments base in DUSEL will be able to search for primordial WIMPs and they would therefore nicely complement the searches at the LHC. The implications of direct and indirect detection of dark matter would thus be far reaching, and their importance for new physics beyond the standard model cannot be overestimated.
- Neutrino Oscillations and Neutrinoless Double-beta Decay
DUSEL would also host experiments in which neutrinos from the Fermi National Accelerator Lab would be detected and have their identity confirmed by detectors based deep underground. Several neutrinoless double-beta decay experiments are also planned at DUSEL. The results from those experiments would allow us to address several fundamental questions in neutrino physics such as: Is there CP violation? What are the precise values of the neutrino mixing angles? What is the origin of neutrino masses? Is the neutrino a Majorana or Dirac particle? Do neutron-antineutron oscillations exist in nature?
- Proton Decay, Neutrinos, and Fundamental Physics
The current lower limit from Super-K on the proton lifetime is close to 1034 yrs. However, many grand unified and superstring theories predict a lifetime for the proton that is about one to two orders of magnitude larger than this value. The discovery of baryon number non-conservation would have profound implications in the quest for unifying the four forces in nature. A large megaton water Cherenkov detector searching for nucleon decay would be a crucial component of the DUSEL enterprise. Experiments based in DUSEL will be able to probe in much greater depth solar and atmospheric neutrinos, neutrinos from supernovae explosions, and from other point sources.
