Quantum Field Theories Coupled to Supergravity: AdS/CFT and Local Couplings

Understand

This article is based on my PhD thesis and covers the following topics: Holographic meson spectra in a dilaton flow background, the mixed Coulomb-Higgs branch in terms of instantons on D7 branes, and a dual description of heavy-light mesons.

• Moreover, in a second part the conformal anomaly of four dimensional supersymmetric quantum field theories coupled to classical N=1 supergravity is explored in a superfield formulation.
• The complete basis for the anomaly and consistency conditions, which arise from cohomological considerations, are given.
• Possible implications for an extension of Zamolodchikov's c-theorem to four dimensional supersymmetric quantum field theories are discussed.
