在U（1）规范不变标量-矢量-张量理论下，我们研究了静态球对称背景下黑洞的性质。在位移对称理论下标量→ + c不变，我们证明了新的毛BH解决方案的存在，一个三阶标量矢量相互作用引起的标量头发周围的事件视界表现出来。在四阶相互作用的存在下，除了立方耦合，也有规则的BH解决方案赋予标量和矢量头发。
Abstract In U (1) gauge-invariant scalar–vector–tensor theories with second-order equations of motion, we study the properties of black holes (BH) on a static and spherically symmetric background. In shift-symmetric theories invariant under the shift of scalar ϕ→ ϕ+ c, we show the existence of new hairy BH solutions where a cubic-order scalar–vector interaction gives rise to a scalar hair manifesting itself around the event horizon. In the presence of a quartic-order interaction besides the cubic coupling, there are also regular BH solutions endowed with scalar and vector hairs.
