Abstract

Up to now there is no evidence of supersymmetric WIMPS dark matter. This may suggests to look for more exotic possibilities, for example compact ultra-dense quark nuggets. Nuclearites are an example of compact objects that could be constituent of the dark matter. After a short discussion on nuclearites, the result of a nuclearite search with the gravitational wave bar detectors NAUTILUS and EXPLORER is reported.

Highlights

During the last decade a very large experimental and theoretical effort has been devoted to understand the problem of dark matter (DM)
Composite objects consisting of light quarks in a color super-conducting phase have been suggested as super-heavy quark nuggets DM; in addition, super-heavy DM anti-quark nuggets could exist and could perhaps solve the matterantimatter asymmetry [1]; the detection of such anti-quark nuggets by cosmic ray experiments is discussed in [2]
The energy loss predicted for super-heavy DM particles varies in different models, but it is likely that such particles could be confused with meteors, since the velocity, 270 km/sec, is in the high-end tail of the meteor velocity distribution

Summary

Introduction

During the last decade a very large experimental and theoretical effort has been devoted to understand the problem of dark matter (DM). The nuclearite search could be an interesting by-product of cosmic ray space experiments looking from space to the light produced in the atmosphere. Due to the uncertainties in the conversion of the energy losses in a measurable signal it is important to have different techniques to detect such exotic particles.
