摘要：
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 models gauged by a U(1)(n) subgroup can be obtained by twisting (ungauged) WZW models. In addition, a class of solutions that describes charged black holes in four dimensions is derived by twisting the SL(2,R)XSU(2) WZW action.
