Black Holes at Accelerators
One of the most surprising and exciting possibilities for new physics at future colliders is the production of microscopic black holes [1], which can occur in theories with large extra dimensions [2]. String theory suggests a scenario in which the Standard Model particles are confined to a submanifold with the familiar three spatial dimensions (the ‘brane’), while gravity is free to propagate i...
متن کاملBlack holes at accelerators
This is my contribution to the proceedings of Stephen Hawking’s 60th birthday celebration. If the ideas of TeV scale gravity are correct, then black holes should be produced at accelerators that probe the TeV scale, and their decays should evidence one of Stephen’s greatest discoveries, the phenomenon of black hole radiance. ∗ email address: [email protected].

متن کاملBlack holes are neither particle accelerators nor dark matter probes.
It has been suggested that maximally spinning black holes can serve as particle accelerators, reaching arbitrarily high center-of-mass energies. Despite several objections regarding the practical achievability of such high energies, and demonstrations past and present that such large energies could never reach a distant observer, interest in this problem has remained substantial. We show that, ...
متن کاملMagnetized Tori of Black Holes
The dynamics of accretion disks around galactic and extragalactic black holes may be influenced by their magnetic field. In this paper we generalize the fully relativistic theory of stationary axisymmetric tori in Kerr metric of Abramowicz et al.(1978) by including strong toroidal magnetic field. This development is particularly important for the general relativistic computational magnetohydrod...
