Detection scenarios for preon stars

Abstract [en]

If subconstituent particles, generically called preons, exist beyond the Standard Model of particle physics (SM), then stable cosmic compact objects, preon stars, with a density of 10^{30} kg/m^3 and above, can exist. This M.Sc. thesis is about finding ways to detect these preon stars, either directly or indirectly. Their eventual observation would be a direct confirmation of particles beyond the SM of today. This indirect detection can even be accomplished way above the energy scale of the soon-to-be started finished Large Hadron Collider (LHC), and in a more inexpensive way. Means of detecting preon stars as they collide with the Earth are discussed, mainly by seismic detection and gravitational effects. The analysis shows that the chances of a typical preon star colliding with the Earth are less than one in the lifetime of the solar system. Therefore detection of preon stars by means of seismic waves seems remote. The impact frequency is however strongly dependent on the preon star mass and size. It should, however, be possible to detect preon stars by means of their induced gravitational perturbations in the solar system, mainly beyond the orbit of Neptune, though it requires more detailed investigation.
