Energy-Charge Dependence for Q-Balls
arXiv:hep-th/0302013 · doi:10.1016/S0550-3213(03)00266-9
Abstract
We show that many numerically established properties of Q-balls can be understood in terms of analytic approximations for a certain type of potential. In particular, we derive an explicit formula between the energy and the charge of the Q-ball valid for a wide range of the charge Q.
