Coset Models Obtained by Twisting WZW Models and Stringy Charged Black Holes in Four Dimensions
David Gershon
We show that several WZW coset models can be obtained by applying O(d,d) symmetry transformations (referred to as twisting) on WZW models. This leads to a conjecture that WZW model…

Exact Solutions of Four Dimensional Black Holes in String Theory
David Gershon
We construct an exact CFT as an SL(2,R)xSU(2)/U(1)^2 gauged WZW model, which describes a black hole in 4 dimensions. Another exact solution, describing a black membrane in 4D (in t…
