The Kavli Institute for Cosmological Physics (KICP) at the University of Chicago is hosting a workshop this winter on the Next-Generation Techniques for Ultra-High Energy (UHE) Astroparticle Physics. The origin of the most energetic particles in the universe could be related to extremely energetic astronomical phenomena or other exotic processes, such as the decay of the super-heavy dark matter in the halo of our galaxy or topological defects created in an early phase of the development of the universe. In order to clarify their origin, it is essential to develop next-generation techniques for detection of their particles by large amounts of statistics. The workshop will address the road map and near-future prospects of cosmic rays and neutrinos above the PeV scale. Included topics are reviews of the latest results, upcoming detectors and techniques, and related theory topics. The anticipated structure is a series of presentations with ample time for discussion and working sessions.
