脏黑洞附近非赤道测地粒子的超高能碰撞
Ultra-high energy collisions of nonequatorial geodesic particles near dirty black holes
摘要：
考虑两个测地粒子围绕旋转静止轴对称黑洞运动的碰撞。它示出了任意非赤道运动，在一定条件下，在他们的质心框架的能量可以增长不受约束（所谓的BSW效应）。这推广了以前关于脏（被物质包围）黑洞的赤道运动和克尔度规的非赤道运动的结果。结果表明，BSW效应发生在视界表面的任何一点附近。我们没有使用克尔度规所特有的时空对称性，所以结果是相当一般的。分类所有可能的情况下的一般方案进行了讨论。
英文摘要：
We consider collision of two geodesic particles moving around rotating stationary axially symmetric black holes. It is shown for arbitrary nonequatorial motion that under certain conditions the energy in their centre of mass frame can grow unbound (the so-called BSW effect). This generalizes the previous results for equatorial motion around dirty (surrounded by matter) black holes and nonequatorial motion around the Kerr metric. It turns out that the BSW effect occurs near any point of the horizon surface. We do not use special symmetries of space-time typical of the Kerr metric, so the results are quite generic. The general scheme classifying all possible scenarios is discussed.
