Abstract:
The ANTARES neutrino telescope is operating in complete configuration since May 2008. Located at a depth between 2400 and 2050 m in the Mediterranean Sea, 40 km off the Provencal coast, it comprises a large three-dimensional array of 885 Optical Modules as well as some acoustic detectors and other instrumentation deployed on 12 vertical lines. The telescope is designed primarily to detect high energy muon neutrinos. The ANTARES detector is also sensitive to a variety of exotic particles, and can provide a unique opportunity for the search for nuclearites.
Nuclearites are super-heavy nuggets of strange quark matter that could be present in cosmic radiation. Their origin is related to energetic astrophysical phenomena (supernovae, collapsing binary strange stars, etc.). Down-going nuclearites could reach the ANTARES depth with velocities ~ 300 km/s, emitting blackbody radiation at visible wavelengths while traversing sea water.
A search strategy for these exotic objects was developed using both simulated and experimental data taken with ANTARES detector in 5 lines configuration, during the year 2007.
