AdS3/LCFT2 - Correlators in new massive gravity

We calculate 2-point correlators for New Massive Gravity at the chiral point and find that they behave precisely as those of a logarithmic conformal field theory, which is characterized in addition to the central charges cL=cR=0 by 'new anomalies' bL=bR=−σ12ℓGN, where σ is the sign of the Einstein-Hilbert term, ℓ the AdS radius and GN Newton's constant.
