Coset models obtained by twisting WZW models and stringy charged black holes in four dimensions.

چکیده
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 U(1) subgroup can be obtained by twisting (ungauged) WZW models. In addition, a class of solutions that describe charged black holes in four dimensions is derived by twisting SL(2, R) × SU(2) WZW action. † e-mail: [email protected]

Exact four-dimensional dyonic black holes and Bertotti-Robinson spacetimes in string theory.
Conformal field theories corresponding to two–dimensional electrically charged black holes and to two–dimensional anti–de Sitter space with a covariantly constant electric field are simply constructed as SL(2, IR)/ZZ WZW coset models. The two–dimensional electrically charged black holes are related by Kaluza–Klein reduction to the 2+1–dimensional rotating black hole of Bañados, Teitelboim and Z...
متن کاملOn the Stability of a Stringy Black Hole
We study the stability under perturbations of a charged four dimensional stringy black hole arising from gauging a previously studied WZW model. We find that the black hole is stable only in the extremal case Q = M . ⋆ email addresses: vaxtov::fucito and [email protected] † Permanent address: Dipartimento di Fisica, Università di Milano, 20133 Milano, Italy and INFN, Sezione di Pavia, Via Ba...
متن کاملSEMICLASSICAL vs. EXACT SOLUTIONS OF CHARGED BLACK HOLE IN FOUR DIMENSIONS AND EXACT O(d, d) DUALITY
We derive a charged black hole solution in four dimensions described by SL(2, R)× SU(2)×U(1)/U(1)2 WZW coset model. Using the algebraic Hamiltonian method we calculate the corresponding solution that is exact to all orders in 1 k . It is shown that unlike the 2D black hole, the singularity remains also in the exact solution, and moreover, in some range of the gauge parameter the space-time does...
متن کاملHeterotic Coset Models of Microscopic Strings and Black Holes
Following a recent conjecture by Lapan, Simons and Strominger, we revisit and discuss an intrinsically heterotic class of conformal field theories, emphasizing their Lagrangian construction as asymmetrically gauged WZW models, which may be useful in several applications to the study of supersymmetric strings and black holes in heterotic and type II string theory compactified on T 6 and K3 × T 2...
متن کامل2d Stringy Black Holes and Varying Constants
Motivated by the recent interest on models with varying constants and whether black hole physics can constrain such theories, two-dimensional charged stringy black holes are considered. We exploit the role of two-dimensional stringy black holes as toy models for exploring paradoxes which may lead to constrains on a theory. A two-dimensional charged stringy black hole is investigated in two diff...
