Novel black holes in higher derivative gravity

We find a class of novel black holes in higher derivative theory. The novel black holes follow behavior of Schwarzschild ones at large mass limit, while dramatically differentiate from Schwarzschild ones for little holes because of the effects which may root in quantum gravity. The temperature of the hole takes maximum for a specific mass, which is related to the new sale introduced in the higher derivative theory, and goes to zero at little mass limit. This property leads to a significant observation that the novel black hole may be a candidate for dark matters evading constraint from gamma-ray burst.

Automated summary

A class of novel black holes in higher derivative theory is discovered. The novel black holes behave like Schwarzschild ones at large mass limit, but significantly differ from Schwarzschild ones for little holes due to the effects potentially rooted in quantum gravity. The temperature of the hole reaches its maximum at a specific mass, related to the new law introduced in the higher derivative theory, and approaches zero at the little mass limit. This property suggests that the novel black hole may be a candidate for dark matters evading constraint from gamma-ray burst.
