摘要：The properties of Q-balls in the complex signum-Gordon model in d spatial dimensions is studied.We obtain a general virial relation for this kind of Q-ball in higher-dimensional spacetime.We compute the energy and radii of a Q-ball with a V-shaped field potential as a function of spatial dimensionality and a parameter defining the model potential energy density to show that this kind of Q-ball can also survive stably in high-dimensional spacetime.
