Stau detection at neutrino telescopes in scenarios with supersymmetric dark matter

Understand

We have studied the detection of long-lived staus at the IceCube neutrino telescope, after their production inside the Earth through the inelastic scattering of high energy neutrinos.

• The theoretical predictions for the stau flux are calculated in two scenarios in which the presence of long-lived staus is naturally associated to viable supersymmetric dark matter.
• Namely, we consider the cases with superWIMP (gravitino or axino) and neutralino dark matter (along the coannihilation region).
• In both scenarios the maximum value of the stau flux turns out to be about 1 event/yr in regions with a light stau.
