# Emission from the D1D5 CFT: higher twists

@article{Avery2009EmissionFT, title={Emission from the D1D5 CFT: higher twists}, author={Steven G. Avery and Borun D. Chowdhury}, journal={Journal of High Energy Physics}, year={2009}, volume={2010}, pages={1-43} }

We study a certain class of nonextremal D1D5 geometries and their ergoregion emission. Using a detailed CFT computation and the formalism developed in [1], we compute the full spectrum and rate of emission from the geometries and find exact agreement with the gravity answer. Previously, only part of the spectrum had been reproduced using a CFT description. We close with a discussion of the context and significance of the calculation.
