Journal ArticleDOI
Hierarchies from fluxes in string compactifications
TL;DR: In this article, the authors show that the hierarchy of scales can be fixed by a choice of Ramond-Ramond and Neveu-Schwarz fluxes in the compact manifold, and give examples involving orientifold compactifications of type IIB string theory and F-theory compactifications on Calabi-Yau fourfolds.
Journal ArticleDOI
High-energy colliders as black hole factories: The End of short distance physics
TL;DR: In the case of the CERN Large Hadron Collider, the high energy black hole cross section grows with energy at a rate determined by the dimensionality and geometry of the extra dimensions as discussed by the authors.
Journal ArticleDOI
Evanescent black holes.
TL;DR: A renormalizable theory of quantum gravity coupled to a dilaton and conformal matter in two spacetime dimensions is analyzed and suggests that the collapsing matter radiates away all of its energy before an event horizon has a chance to form, and black holes disappear from the quantum-mechanical spectrum.
Journal ArticleDOI
Classical black hole production in high-energy collisions
TL;DR: The existence of an apparent horizon is related to the solution of an unusual boundary-value problem for Poisson's equation in flat space as discussed by the authors, which provides improved estimates of the classical cross section for black hole production and of the mass of the resulting black holes.
Journal ArticleDOI
Loss of Incoherence and Determination of Coupling Constants in Quantum Gravity
TL;DR: In this paper, the wave function of an interacting family of one large parent and many Planck-sized "baby" universes is computed in a semiclassical approximation using an adaptation of Hartle-Hawking initial conditions.
