Search for Nuclearites with IceCube — •Nick Jannis Schmeißer1 and Jonas Häußler2 for the IceCube collaboration — 1Bergische Universität Wuppertal — 2RWTH Aachen
Nuclearites are lumps of strange quark matter that were first proposed in the 1980s. Strange quark matter consists of roughly equal amounts of up-, down-, and strange-quarks and could appear in the Standard model at high densities as well as in BSM theories. They are candidates for the cold dark matter observed in the Universe. We are presenting the first search for nuclearites with IceCube. The IceCube Neutrino Observatory is expected to have the best sensitivity to nuclearites due to its size and lower noise rate in comparison to other neutrino telescopes.
This presentation gives a short motivation for nuclearites and discusses their properties and the signature they are expected to produce in the IceCube detector, which are thermal shocks produced by atomic collisions in the Antarctic ice. The analysis chain used to search for nuclearites is discussed, leading to the first sensitivities of the IceCube detector for different nuclearite masses.
