Entropy and Action of Dilaton Black Holes

Renata Kallosh, Tomas Ortin, Amanda Peet

We present a detailed calculation of the entropy and action of dilaton black holes, and show that both quantities coincide with one quarter of the area of the event horizo…

Dilaton Black Holes Near the Horizon

Renata Kallosh, Amanda Peet

Generic 4-d black holes with unbroken supersymmetry are shown to tend to a Robinson-Bertotti type geometry with a linear dilaton and doubling of unbroken supersymmet…

Cosmic Censorship in Two-Dimensional Gravity

J. Russo, L. Susskind, L. Thorlacius

A weak version of the cosmic censorship hypothesis is implemented as a set of boundary conditions on exact semi-classical solutions of two-dimensional dilaton gravity. These bounda…

Electric-Magnetic Duality and Supersymmetry in Stringy Black Holes

Tomás Ortín

We present a generalization of the charged dilaton black holes family whose main feature is that both fields have electric and magnetic charges, the axion field s…

Aspects of Nonrenormalizable Terms in a Superstring Derived Standard--like Model

Alon E. Faraggi

I investigate the role of nonrenormalizable terms, up to order N=8, in a superstring derived standard--like model. I argue that nonrenormalizable terms restrict the gauge symmetry,…

The Endpoint of Hawking Evaporation

J. Russo, L. Susskind, L. Thorlacius

The formation and semi-classical evaporation of two-dimensional black holes is studied in an exactly solvable model. Above a certain threshold energy flux, collapsing matter forms…
