The Passage of Ultrarelativistic Neutralinos through the Matter of the Moon

Abstract

I consider the prospect to use the outer layer of the Moon as a detector volume for ultra-high energy (UHE) neutrino fluxes and the flux of the lightest neutralino which I assume is the lightest supersymmetric particle (LSP). For this purpose, I calculate the event rates of these fluxes for top-down scenarios. I show that a suitable experiment for the detection of radio waves might be able to detect sufficient event rates after a measurement period of one year.
