The Spectrum of Sl(2, R)/U(1) Black Hole Conformal Field Theory
Dileep P. Jatkar
Abstract
We study string theory in the background of a two-dimensional black hole which is described by an SL(2, R)/U(1) coset conformal field theory. We determine the spectrum of this conformal field theory using supersymmetric quantum mechanics and give an explicit form of the vertex operators in terms of the Jacobi functions. We also discuss the applicability of SUSY quantum mechanics techniques to non-linear σ-models.
