Giants on Deformed Backgrounds Part II: The Gauge Field Fluctuations

Understand

We study the full bosonic spectrum around giant and dual giant graviton probes in exactly marginally deformed backgrounds.

• Considering supersymmetric and non-supersymmetric three-parameter deformations of AdS_5 X S^5, we perform a detailed analysis of small fluctuations for both the expanded D3-brane configurations.
• In particular, we enhance the scalar spectra of frequencies found in our previous paper hep-th/0609173 with the important contributions brought by the gauge field fluctuations.
• The giant graviton case exhibits a non-trivial coupling between scalar and vector modes driven by the deformation, whose resolution yields to a universal correction of the undeformed spectrum.
