Probing a Supersymmetric Model for Neutrino Masses at Ultrahigh Energy Neutrino Telescopes
arXiv:0712.1711 · doi:10.1016/j.physletb.2008.02.065
Abstract
A bilinear R-Parity breaking SUSY model for neutrino mass and mixing predicts the lightest superparticle to decay mainly into a pair of tau leptons or b quarks along with a neutrino for relatively light SUSY spectra. This leads to a distinctive triple bang signature of SUSY events at ultrahigh energy neutrino telescopes like IceCube or Antares. While the expected signal size is only marginal at IceCube, it will be promising for a future multi-km^3 size neutrino telescope.
