我们研究高维黑洞周围的高能粒子碰撞。结果表明，如果满足以下两个条件，则在事件视界附近，像四维的巴尼亚多斯、丝绸和韦斯特（BSW）过程一样，质心能量可以任意大：（i）视界处于极值；（ii）两个碰撞粒子中的任何一个的参数都经过微调，这称为临界粒子条件。我们还表明，对于简单的情况，满足临界粒子条件的测试粒子可以从遥远的区域到达事件视界。最后，我们讨论了 BSW 过程与极值黑洞周围测试场的线性不稳定性之间的关系，后者最近由 Aretakis [Commun.数学。物理。 307, 17 (2011);安.研究所。亨利·庞加莱 12, 1491 (2011)； J.函数。肛门。 263、2770（2012）； arXiv：1206.6598；经典量子引力 30, 095010 (2013);物理。修订版 D 87, 084052 (2013)]。
We study high energy particle collisions around higher dimensional black holes. It is shown that the center of mass energy can be arbitrarily large in the vicinity of the event horizon like the Bañados, Silk and West (BSW) process in four dimensions if the following two conditions are satisfied: (i) the horizon is extremal and (ii) the parameters of either of the two colliding particles are fine-tuned, which is called a critical particle condition. We also show that a test particle which satisfies the critical particle condition can reach the event horizon from a distant region for a simple case. Finally, we discuss the relation between the BSW process and the linear instability of test fields around extremal black holes, the latter of which has been recently found by Aretakis [Commun. Math. Phys. 307, 17 (2011); Ann. Inst. Henri Poincaré 12, 1491 (2011); J. Funct. Anal. 263, 2770 (2012); arXiv:1206.6598; Classical Quantum Gravity 30, 095010 (2013); Phys. Rev. D 87, 084052 (2013)].
