Abstract

Excited Q-balls are studied by numerical simulations in the Minimal Supersymmetric Standard Model with supersymmetry broken by a gravity mediated mechanism. It is found that there is a suppression factor of \cO(102)\cO(10^{-2}) in the rate at which a Q-ball can emit their excess energy compared to the rate set by the dynamical scale of the field, mm. Furthermore, it is noted that a Q-ball can withstand a large amount of excess energy without losing a significant amount of its charge. The cosmological importance of these properties are considered for Q-balls in the thermal bath of the early universe.
