摘要

如果对撞粒子的角动量微调到临界值，那么两个对撞粒子的质心能量在极值迈尔斯-佩里黑洞的事件视界附近可以达到任意高的水平。我们研究了两个碰撞粒子在四维和六维的最大效率。两个粒子在四维克尔黑洞附近的碰撞效率是130%。我们表明，在六维空间中碰撞的效率增加到了 145%。我们还表明，当时空维度增加时，粒子能达到高能量的极角区域更大。

Effeciency of higher dimensional black holes as particle accelerators

The center-of-mass energy of two colliding particles could be arbitrarily high in the vicinity of event horizons of the extremal Myers-Perry black holes if the angular momentum of colliding particles is fine-tuned to the critical values. We investigate the maximum efficiency of two colliding particles in four and six dimensions. The efficiency of collision for two particles near the four-dimensional Kerr black holes is 130%. We show that the efficiency increases to 145% for collision in six dimensions. We also show that the region for the polar angle in which the particle can reach the high energy is larger when the dimension of space-time increases.
