Abstract:
The Very Large Volume Neutrino Telescopes that will become operational in the near future provide the possibility of detecting massive exotic particles in the cosmic radiation, like nuclearites. These are hypothetical stable particles of strange matter, composed of approximately equal amounts of up, down and strange quarks. They are essentially neutral, the small electric charge of the strange matter core could be compensated by electrons in weak equilibrium inside the quark core, or forming a cloud around smaller nuclearites. The typical velocities of the massive nuclearites gravitationally trapped in the Galaxy are ¦Â¡Ö10-3. The large nuclearites interact mainly through elastic collisions with the atoms of the traversed media, with an energy loss described by: dE/dx=¨C¦Ò¦Ñmedv2. The ANTARES underwater neutrino telescope could detect the black body radiation emitted along the over-heated path of the nuclearite. For 1013 GeV¡Ü MNucl ¡Ü1022 GeV, the nuclearites could reach the ANTARES detector from above. The study discusses the trigger requirements implied for nuclearite event detection
with ANTARES and also presents the upper flux limits attainable by ANTARES (in complete configuration) in one year of operation.
