TL;DR
This paper investigates superradiant scattering of massive scalars by rotating mini black holes with a mirror boundary, exploring conditions for black-hole bombs and potential LHC formation, highlighting effects on brane emissions and angular momentum.
Contribution
It introduces the concept of black-hole bombs with mirror boundary conditions for mini black holes and analyzes their emissions, including implications for collider physics.
Findings
Brane emissions dominate for lower angular modes with lighter mass.
Superradiance leads to exponential energy transfer from black holes.
Black-hole bombs could potentially form at the LHC.
Abstract
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.
