摘要:

本文研究了2+1维BTZ黑洞视界附近两个不同能量粒子的超高能碰撞效应(BSW效应)。我们发现具有临界角动量的粒子可以存在于BTZ黑洞的外视界内,而与粒子的能量无关。因此,对于非极值BTZ黑洞,通过对以粒子运动为特征的参数进行微调,在内视界上的BSW过程是可能的。而对于极端BTZ黑洞,具有临界角动量的粒子只能存在于简并视界上,在那里也可能发生BSW过程。

英文摘要:

In this paper, we study the effect of ultra-high energy collisions of two particles with different energies near the horizon of a 2+1 dimensional BTZ black hole (BSW effect). We find that the particle with the critical angular momentum could exist inside the outer horizon of BTZ black hole regardless of the particle energy. Therefore, for the non-extremal BTZ black hole, the BSW process is possible on the inner horizon with the fine tuning of parameters which are characterized by the motion of particle. While for the extremal BTZ black hole, the particle with the critical angular momentum could only exist on the degenerate horizon, and the BSW process could also happen there.
