R^2 Corrections to Black Ring Entropy

High Energy Physics - Theory 2007-05-23 v2

Abstract

Recently, Guica, Huang, Li, and Strominger considered an R^2 correction to the entropy of a black ring, and found a mismatch between supergravity and the CFT. However, such a comparison should take into account the subtle distinction between the asymptotic charges of the black ring and the charges entering the CFT description. We show that using the correct charges yields perfect agreement.
