R 2 corrected AdS2 holography

A bstract We approach the problem of constructing an explicit holographic dictionary for AdS 2 /CFT 1 correspondence in context higher derivative gravitational actions AdS2 space-times. These are obtained by S reduction four-dimensional $$ \mathcal{N} N = Wilsonian effective with Weyl squared interactions restricted to constant scalar backgrounds. BPS black hole near-horizon space-times fall into this class backgrounds, and identifying boundary operators dual bulk fields, we explicitly show how Wald entropy is holographically encoded anomalous transformation operator a composite field. Additionally, using 2d/3d lift, that CFT naturally embedded chiral half 3 space-time, identify specific encodes central charge .
