Holographic Correlators in a Flow to a Fixed Point | | Marcus Berg

23 Sep 2002 | | Journal: | JHEP 0212 (2002) 070 | | Subject: | hep-th | | Abstract: | Using holographic renormalization, we study correlation functions throughout a renormalization group flow between two-dimensional superconformal field theories. The ultraviolet theory is an N=(4,4) CFT which can be thought of as a symmetric product of U(2) super WZW models. It is perturbed by a relevant operator which preserves one-quarter supersymmetry and drives the theory to an infrared fixed point. We compute correlators of the stress-energy tensor and of the relevant operators dual to supergravity scalars. Using the former, we put together Zamolodchikov’s C function, and contrast it with proposals for a holographic C function. In passing, we address and resolve two puzzles also found in the case of five-dimensional bulk supergravity. | | Source: | arXiv, hep-th/0209191 | | Services: | Forum | Review | PDF | Favorites | |
