论文摘要
我们提出了一类高衍生的重力,可以将其视为Starobinsky模型的高斯 - 骨网延伸。该理论承认了Minkowski时空真空,其线性光谱由Graviton组成和大规模的标量模式。除了通常的Schwarzschild黑洞外,我们还使用数值分析来确定在某些合适的质量范围内,携带巨大标质头发的新黑洞可能会出现。新的黑洞用作“墙”,将裸的时空奇异性和虫洞分开,在标量头发的参数空间中。我们的数值结果还表明,尽管新的毛茸茸的黑洞和Schwarzschild具有不同的时空几何形状,但它们的熵和温度对于相同的质量是相同的。
We propose a class of higher-derivative gravities that can be viewed as the Gauss-Bonnet extension of the Starobinsky model. The theory admits the Minkowski spacetime vacuum whose linear spectrum consists of the graviton and a massive scalar mode. In addition to the usual Schwarzschild black hole, we use numerical analysis to establish that in some suitable mass range, new black holes carrying the massive scalar hair can emerge. The new black hole serves as a "wall" separating the naked spacetime singularity and wormholes in the parameter space of the scalar hair. Our numerical results also indicate that although the new hairy black hole and the Schwarzschild have different spacetime geometry, their entropy and temperature are same for the same mass.
