New Constraints on Supersymmetry Using Neutrino Telescopes

Understand

We demonstrate that megaton-mass neutrino telescopes are able to observe the signal from long-lived particles beyond the Standard Model, in particular the stau, the supersymmetric partner of the tau lepton.

• Its signature is an excess of charged particle tracks with horizontal arrival directions and energy deposits between 0.1 and 1 TeV inside the detector.
• We exploit this previously-overlooked signature to search for stau particles in the publicly available IceCube data.
• The data shows no evidence of physics beyond the Standard Model.
