论文摘要
最近，HOD证明了一个无关定理，即静态标量场不能在渐近平坦的背景中形成球形对称的玻色子星。另一方面，标量字段可以根据近代领先的Ginzburg-Landau型号耦合到梯度。在目前的工作中，我们通过考虑静态标量字段与场梯度之间的耦合来扩展HOD的讨论。对于非阴性耦合参数，我们表明没有由耦合静态标量场制成的渐近平面球形对称的玻色子星。
Recently Hod proved a no-go theorem that static scalar fields cannot form spherically symmetric boson stars in the asymptotically flat background. On the other side, scalar fields can be coupled to the gradient according to next-to-leading order Ginzburg-Landau models. In the present work, we extend Hod's discussions by considering couplings between static scalar fields and the field gradient. For a non-negative coupling parameter, we show that there is no asymptotically flat spherically symmetric boson stars made of coupled static scalar fields.
