AdS_3/LCFT_2 - Correlators in New Massive Gravity

TL;DR

This paper computes 2-point correlators in New Massive Gravity at the chiral point, revealing they match a logarithmic conformal field theory with specific anomalies and zero central charges.

Contribution

It demonstrates that correlators in New Massive Gravity correspond to a logarithmic CFT with explicit anomaly values at the chiral point.

Findings

Correlators behave as in a logarithmic CFT

Central charges are zero, anomalies are non-zero

Results match theoretical predictions for LCFT behavior

Abstract

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 c_L = c_R = 0 by `new anomalies' b_L = b_R = -\sigma\frac{12\ell}{G_N}, where \sigma is the sign of the Einstein-Hilbert term, \ell the AdS radius and G_N Newton's constant.
