镜面小黑洞的超辐射
Superradiance by mini black holes with mirror
摘要：
研究了旋转小黑洞对大质量标量粒子的超辐射散射。在镜像边界条件下，系统变成了所谓的黑洞炸弹，其中黑洞的旋转能量随时间呈指数规律地传递给散射粒子。整体排放以及膜排放被认为是一起。结果表明，对于质量较轻、角动量较大的低角模，黑洞的膜辐射效应最大。讨论了在LHC上形成黑洞弹的可能性。
英文摘要：
The superradiant scattering of massive scalar particles by a rotating mini black hole is investigated. Imposing the mirror boundary condition, the system becomes the so called black-hole bomb where the rotation energy of the black hole is transferred to the scattered particle exponentially with time. Bulk emissions as well as brane emissions are considered altogether. It is found that the largest effects are expected for the brane emission of lower angular modes with lighter mass and larger angular momentum of the black hole. Possibilities of the forming the black-hole bomb at the LHC are discussed.
