论文摘要
我们考虑了四维渐近平坦黑洞的准模式和鹰式辐射，在最笼统的狂热界界界界界界与非依赖性的爱因斯坦重力理论中，在恒定背景上与爱因斯坦理论共享其重力谱。我们表明，一旦与立方术语耦合，抑制了标量，电磁和狄拉克场的抑制速率和真实振荡频率。霍金辐射的强度也被抑制，从而大致导致在足够大的耦合常数下更长的寿命。
We consider quasinormal modes and Hawking radiation of four-dimensional asymptotically flat black holes in the most general up to-cubic-order-in-curvature dimension-independent Einsteinian theory of gravity that shares its graviton spectrum with the Einstein theory on constant curvature backgrounds. We show that damping rate and real oscillation frequencies of quasinormal modes for scalar, electromagnetic and Dirac fields are suppressed once the coupling with the cubic term is on. The intensity of Hawking radiation is suppressed as well, leading to, roughly, one order longer lifetime at a sufficiently large coupling constant.
