Accurate predictions of decay constants

Extension of holographic methods to heavy mesons

Abstract

We study the mass spectrum and decay constants of light and heavy mesons in a soft-wall holographic approach, using the correspondence of string theory in Anti-de Sitter space and conformal field theory in physical space-time.
