The charges of a twisted brane

Matthias R Gaberdiel, Terry Gannon

The charges of the twisted D-branes of certain WZW models are determined. The twisted D-branes are labelled by twisted representations of the affine algebra, and their charge is si…

Quark-like potentials in an extended Maxwell theory

Harry Schiff

The exact Linard-Wiechert solutions for the point charge in arbitrary motion are shown to be null fields everywhere. These are used as a basis to introduce extended elec…

Comments on nonunitary conformal field theories

T. Gannon

As is well-known, nonunitary RCFTs are distinguished from unitary ones in a number of ways, two of which are that the vacuum 0 doesn't have minimal conformal weight, and that the v…

Anthropic Estimates of the Charge and Mass of the Proton

Don N. Page

By combining a renormalization group argument relating the charge e and mass m of the proton by e^2 ln m ~ 0.1 pi (in Planck units) with the Carter-Carr-Rees anthropic argument tha…

Nearly Degenerate dS Horizons from a 2-D Perspective

A. J. M. Medved

Some recent studies have implied that quantum fluctuations will prevent a near-extremal black hole from ever attaining a state of precise extremality. In this paper, we consider th…

Of Bounces, Branes and Bounds

A. J. M. Medved

Some recent studies have considered a Randall-Sundrum-like brane world evolving in the background of an anti-de Sitter Reissner-Nordstrom black hole. For this scenario, it has been…

Schwinger Pair Production in Electric and Magnetic Fields

Sang Pyo Kim, Don N. Page

Charged particles in static electric and magnetic fields have Landau levels and tunneling states from the vacuum. Using the instanton method of Phys. Rev. D 65, 105002 (2002), we o…
