标题： Black hole minimum size and scalar charge in shift-symmetric theories

摘要： 已知对于位移对称标量而言，只有与高斯-博内不变量的线性耦合才能引入黑洞毛发。 这种带有毛发的黑洞有一个最小质量，该质量由这种相互作用的耦合确定，并且标量电荷由其质量和自旋唯一确定，前提是该耦合值固定。 在这里，我们探讨额外的位移对称相互作用如何影响黑洞的结构、最小质量的值以及标量电荷。 显示英文摘要

摘要： It is known that, for shift-symmetric scalars, only a linear coupling with the Gauss-Bonnet invariant can introduce black hole hair. Such hairy black holes have a minimum mass, determined by the coupling of this interaction, and a scalar charge that is uniquely determined by their mass and spin for a fixed value of that coupling. Here we explore how additional shift-symmetric interactions affect the structure of the black hole, the value of the minimum mass, and the scalar charge.
