Holographic RG flows and nearly-marginal operators (1310.0858v2)
Published 2 Oct 2013 in hep-th, cond-mat.str-el, and hep-ph
Abstract: The holographic renormalization group flows associated with marginally relevant operators are analyzed. The associated perturbative and non-perturbative beta-functions are calculated and the consistent scalar potentials are identified. The presence of a Zamolodchikov metric in the multiscalar case is shown to affect beta-functions starting at two loops.
