3 Looking for SUSY in the Ice SUSY Breaking mechanism mass spectrum LSP LSP is determined by the scale of SUSY breaking ( F ) 10 3 GeV < F < GeV F > GeV LSP is neutralino F < GeV LSP is gravitino in most of these cases: NLSP is charged slepton (typically the τ R with m = ϑ(150 GeV) for F > 10 6 GeV and HE collisions, NLSPs travel long distances before decaying I.A., G.Burdman, Z.Chacko - PRL TeV Particle Physics and Physics Beyond the Standard Model p.3/29

The last three columns correspond to upgoing NLSP pair events, for three different choices of squark masses: 300 GeV, 600 GeV and 900 GeV. Z.

18 Detection of Cosmic Neutrinos Muon tracks (ICECUBE, RICE) Electromagnetic and Hadronic Showers (ICECUBE, RICE, ANITA, Auger, OWL, EUSO) To determine the energy flux (muons or showers) that reaches the detector we need to consider propagation of neutrinos and leptons through the Earth and ice ν τ give different contribution from ν µ due to the very short τ lifetime, i.e. the regeneration effect. New physics may be manifested via production of new particles in neutrino interactions, such as supersymmetric charged sleptons, staus, which after interactions with matter produce charge tracks similar to muons, or hardonic showers.
