事件视界附近的高能正碰粒子:情景分类

High energy head-on particle collisions near event horizons: classifcation of scenarios

H. V. Ovcharenko, O. B. Zaslavskii

AI总结:

本文研究事件视界附近向外与向内粒子的正碰,依据粒子1到视界的固有时区分白洞与黑洞,并分类自由或受有限力作用的情景,给出质心能量无界增长的条件。

摘要:

我们考虑两个粒子在事件视界附近发生正碰。粒子1向外运动,粒子2向内运动。我们阐明了在何种情况下质心系能量 E_{c.m.} 可以无限制增长。如果对粒子1而言,视界与其外任意一点之间的固有时是有限的,我们处理的就是白洞;如果该固有时是无限的,我们处理的就是黑洞。粒子可以是自由的,也可以受到有限力的作用。我们的结果与粒子沿相同方向运动时标准 BSW 效应的结果互补。这些结果依赖于我们此前工作 H.V. Ovcharenko、O.B. Zaslavskii,Phys. Rev. D 108, 064029 (2023) 中建立的粒子分类。

英文摘要:

We consider head-on collisions of two particles near the event horizon. Particle 1 is outgoing, particle 2 is ingoing. We elucidate, in which case the energy $E_{c.m.}$ in the center of mass frame can grow unbounded. If the proper time between the horizon and an arbitrary point outside it for particle 1 is finite, we deal with a white hole. If it is infinite, we deal with a black hole. Particles can be either free or experience the action of a finite force. Our results are complementary to those for the standard BSW effect when particles move in the same direction. The results rely on classification of particles developed in our previous work H.V. Ovcharenko, O.B. Zaslavskii, Phys. Rev. D 108, 064029 (2023).
