Abstract:
ANTARES is the largest underwater neutrino telescope in the Northern Hemisphere and is taking data in complete configuration since 2008. While designed to observe high energy neutrinos from non-terrestrial sources, ANTARES can also be used to search for nuclearites. These are hypothetical massive lumps of strange quark matter that may be present in the cosmic radiation, and having typical velocities of about 300 km/s. Nuclearites would interact with the surrounding media through elastic and quasi elastic collisions, and could be detected by means of the black-body radiation in underwater telescopes.
This work presents a strategy to search for nuclearites using data taken in 2007 and 2008. No candidate event was found and upper limits on the nuclearite flux were established.
