论文摘要
我们考虑在极端旋转的轴向对称中性的黑洞中产生3和4的极端旋转轴向对称的中性的黑洞3和4的地平线附近的两个颗粒1和2的碰撞。我们讨论了颗粒3和4粒子3和4落入黑洞并在白洞区域移动的情况。如果粒子1进行了微调，则质量中心的能量$ e_ {c.m。} $会生长无限（Bañados-Silk-West效应）。然后，粒子3 \原则上可以到达另一个宇宙中的平坦无穷大。如果不仅$ e_ {c.m。} $，而且相应的杀戮能源$ e $是无限的，这给出了所谓的超级碳过程（SPP）。我们证明SPP \确实是可能的。因此，白孔被证明是从一个宇宙转移到另一个宇宙的高能通量的潜在来源。这概括了Patil和Harada为Kerr指标制作的最新观察。我们在不同尺度上分析了该过程的两个不同制度。
We consider collision of two particles 1 and 2 near the horizon of the extremal rotating axially symmetric neutral generic black hole producing particles 3 and 4. We discuss the scenario in which both particles 3 and 4 fall into a black hole and move in a white hole region. If particle 1 is fine-tuned, the energy $E_{c.m.}$ in the centre of mass grows unbounded (the Bañados-Silk-West effect). Then, particle 3 \ can, in principle, reach a flat infinity in another universe. If not only $E_{c.m.}$ but also the corresponding Killing energy $E$ is unbounded, this gives a so-called super-Penrose process (SPP). We show that the SPP\ is indeed possible. Thus white holes turn out to be potential sources of high energy fluxes that transfers from one universe to another. This generalizes recent observaitons made by Patil and Harada for the Kerr metric. We analyze two different regimes of the process on different scales.
