# Q-Ball Condensation

Abstract : Q-balls arise in particle theories with $U(1)$ global symmetry. The coupling of the corresponding scalar field to fermions leads to Q-ball evaporation. In this paper we consider the oposite problem, the case where a Q-ball absorbs particles to grow. In particular we shall use the exact quantum mechanical description of fermions interacting with a Q-ball to solve the problem. Results show that Q-ball condensation can be another mechanism for Q-ball creation.
