对于赤道轨道的情况，计算了在极端克尔黑洞的粒子视界附近的密度尖峰附近的弱相互作用粒子的碰撞中产生的无质量粒子在无穷远处的逃逸分数。我们与Schwarzschild的情况进行了比较，并认为在极端黑洞的情况下，可以产生红移信号，这可能会探索质心能量范围超出任何可行的地球加速器的粒子碰撞的物理。
The escape fraction at infinity is evaluated for massless particles produced in collisions of weakly interacting particles accreted into a density spike near the particle horizon of an extremal Kerr black hole, for the case of equatorial orbits. We compare with the Schwarzschild case, and argue that in the case of extremal black holes, redshifted signatures can be produced that could potentially explore the physics of particle collisions at center of mass energies that extend beyond those of any feasible terrestrial accelerator.
