Gauge bosons and the AdS3/LCFT2 correspondence

We study the relationship between the gauge boson coupled to spin 2 operator and the singleton in three-dimensional anti-de Sitter space(AdS(3)). The singleton can be expressed in terms of a pair of dipole ghost fields A and B which couple to D and C operators on the boundary of AdS(3). These operators form the logarithmic conformal field theory(LCFT2). Using the correlation function for logarithmic pair, we calculate the greybody factor for the singleton. In the low temperature limit of omega >> T+/-, this is compared with the result of the bulk AdS3 calculation of the gauge boson. We find that the gauge boson cannot be realized as a model of the AdS(3)/LCFT2 correspondence.
