Query: Superradiance by mini black holes with mirror   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.
