Escape of superheavy and highly energetic particles produced by particle collisions near maximally charged black holes
Hiroya Nemoto, Umpei Miyamoto, Tomohiro Harada +1
For particle collision near rapidly rotating Kerr black holes, the center-of-mass energy can be arbitrarily high if the angular momentum of either of the colliding particles is fin…
Upper limits of particle emission from high-energy collision and reaction near a maximally rotating Kerr black hole
Tomohiro Harada, Hiroya Nemoto, Umpei Miyamoto
The center-of-mass energy of two particles colliding near the horizon of a maximally rotating black hole can be arbitrarily high if the angular momentum of either of the incident p…
Naked Singularity Explosion in Higher Dimensions
Umpei Miyamoto, Hiroya Nemoto, Masahiro Shimano
Motivated by the recent argument that in the TeV-scale gravity trans-Planckian domains of spacetime as effective naked singularities would be generated by high-energy particle (and…
Particle Creation by Naked Singularities in Higher Dimensions
Umpei Miyamoto, Hiroya Nemoto, Masahiro Shimano
Recently, the possibility was pointed out by one of the present authors and his collaborators that an effective naked singularity referred to as "a visible border of spacetime" is…
