众所周知，对于位移对称标量，只有高斯-邦纳（GB）不变量的线性耦合才能引入黑洞头发。这样的多毛黑洞有一个最小质量，由这种相互作用的耦合决定，和一个标量电荷，唯一地由它们的质量和自旋决定，对于一个固定的耦合值。在这里，我们探讨如何额外的移位对称的相互作用影响的黑洞的结构，最小质量的值，和标量电荷。
It is known that, for shift-symmetric scalars, only a linear coupling with the Gauss–Bonnet (GB) 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.
