Abstract:
The Strange quark matter (SQM) was introduced by Edward Witten in 1984 as a hypothetical type of matter composed of approximately equal quantities of up, down and strange quarks, which has a slightly higher density than that of nuclear matter. Massive SQM particles are called nuclearites. Nuclearites enter in the Earth atmosphere with typical galactic velocities of about 250 km/s. The SQM particles with masses higher than 1013 GeV could reach the Earth and interact with atoms and molecules of sea water within the sensitive volume of the deep-sea neutrino telescopes. Thus, the massive SQM particles can be detected with the KM3NeT detector (whose first detection units are already installed in the Mediterranean Sea and taking data) through the visible blackbody radiation generated along their path inside the instrumented area. In this work, the results of a study using Monte Carlo simulations of down-going nuclearites are presented.
