Energy Losses of Q-balls

Abstract

After a short review of Q-balls properties, in this paper we discuss their interaction with matter, and their energy losses in the earth, for a large range of velocities. These calculations are used to compute the fractional angular acceptance of a detector located at Gran Sasso Laboratory. Furthermore we computed the light yield in liquid scintillators, the ionization in streamer tubes and the Restricted Energy Loss in the CR39 nuclear track detector.
