虫洞附近高能粒子碰撞的新情景

New scenarios of high-energy particle collisions near wormholes

O. B. Zaslavskii

摘要:

我们提出了两个新的方案,在虫洞的背景下的高能粒子碰撞。在场景1中,新颖之处在于效果不需要来自不同嘴的两个粒子。相反,当实验者从喉咙的同一侧向虫洞发送粒子时,所有这些高能碰撞的场景都会出现。对于静态虫洞,这种方法会导致在质心产生无限大的能量。对于旋转的虫洞,它使得超级彭罗斯过程(在无穷远处测量的无限能量)成为可能。在场景2中,一个碰撞粒子从一开始就在虫洞喉部附近振荡。在这个意义上,场景2介于标准场景和场景1之间,因为所讨论的粒子根本不是来自无穷远。

英文摘要:

We suggest two new scenarios of high-energy particle collisions in the background of a wormhole. In scenario 1 the novelty consists in that the effect does not require two particles coming from different mouths. Instead, all such scenarios of high energy collisions develop, when an experimenter sends particles towards a wormhole from the same side of the throat. For static wormholes, this approach leads to indefinitely large energy in the center of mass. For rotating wormholes, it makes possible the super-Penrose process (unbounded energies measured at infinity). In scenario 2, one of colliding particles oscillates near the wormhole throat from the very beginning. In this sense, scenario 2 is intermediate between the standard one and scenario 1 since the particle under discussion does not come from infinity at all.
