Abstract

We study D-branes in the mirror pair N = 2 Liouville/supersymmetric SL(2,ℝ)/U(1) coset superconformal field theories. We build D0-, D1- and D2-branes, on the basis of the boundary state construction for the H₃ ⁺ conformal field theory. We also construct D0-branes in an orbifold that rotates the angular direction of the cigar. We show how the poles of correlators associated to localized states and bulk interactions naturally decouple in the one-point functions of localized and extended branes. We stress the role played in the analysis of D-brane spectra by primaries in SL(2,ℝ)/U(1) which are descendents of the parent theory.
