Abstract:
ANTARES is a neutrino telescope aimed at the detection of high energy cosmic neutrinos. The ANTARES detector is located on the floor of the Mediterranean Sea, near the French city of Toulon, and is taking data in complete configuration since 2008. It consists of a photomultiplier array distributed on 12 vertical lines, optimized for the detection of the Cherenkov light produced by up-going induced muons. The ANTARES telescope provides also a tool to search for exotic particles, such as nuclearites and magnetic monopoles. Nuclearites are hypothetical massive particles, composed of nearly equal numbers of up, down and strange quarks. They have a velocity characteristic to the objects gravitationally trapped in our galaxy, and interact with the surrounding medium via elastic and quasi-ellastic collisions. As they pass slowly through the water, they would produce a thermal shock emitting blackbody radiation at visible wavelengths. We have searched for nuclearites using the ANTARES data taken in 2007 and 2008, in the 5 line and 12 line configurations, respectively. The preliminary upper limits on the nuclearite flux will be presented.
