Exotic Signatures from Physics Beyond the Standard Model in IceCubeSignal and Background Simulations
Abstract
Cosmic rays reach the atmosphere with energies up to 10" GeV and high energy neutrinos are expected to reach similar energy regions. The incident particle may interact with a nucleon within the atmosphere or inside the Earth to produce exotic particles, thereby probing physics beyond the Standard Model (SM). Attractive scenarios are, for example, supersymmetric extensions of the SM (SUSY) or Kaluza-Klein models. Under favorable conditions meta-stable, charged SUSY or Kaluza-Klein particles give rise to well-separated, parallel, minimum ionizing tracks in IceCube. Since background events from charm and bottom decays and Drell-Yan processes inside the air shower as well as coincident neutrino events could lead to similar signatures, these events are expected to form a relevant background. As the production of exotic particles is highly suppressed, the understanding of this di-muon background seems to be crucial for an analysis in IceCube.
