Interactions in the Sl(2,ir)/u(1) Black Hole Background


We calculate twoand three-point tachyon amplitudes of the SL(2,IR)/U(1) twodimensional Euclidean black hole for spherical topologies in the continuum approach proposed by Bershadsky and Kutasov. We find an interesting relation to the tachyon scattering amplitudes of standard non-critical string theory. ⋆ † Permanent Address: Universität Bonn, Physikalisches… (More)
