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.

高维黑洞作为粒子加速器的效率

如果将碰撞粒子的角动量微调到临界值，则两个碰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能任意高。我们研究了两个碰撞粒子在四维和六维中的最大效率。四维克尔黑洞附近两个粒子的碰撞效率为130%。我们表明，六维碰撞的效率提高到 145%。我们还表明，当时空维度增加时，粒子可以达到高能量的极角区域更大。
