A note on dilaton absorption and near-infrared D3 brane holography

TL;DR

This paper shows that subleading corrections to dilaton absorption by D3-branes, previously computed via supergravity, can be exactly reproduced using a deformed N=4 SYM theory, supporting the robustness of holographic duality.

Contribution

It demonstrates the exact match of supergravity corrections with a worldvolume calculation in a deformed N=4 SYM, suggesting holography extends beyond the near horizon limit.

Findings

Supergravity and worldvolume calculations agree on subleading corrections.

Deformation by a dimension eight operator reproduces supergravity results.

Holographic duality may hold beyond the near horizon approximation.

Abstract

We consider the first subleading terms in the low-energy cross section for the absorption of dilaton partial waves by D3-branes. We demonstrate that these corrections, computed previously via supergravity, can be reproduced exactly in a worldvolume calculation using a deformation of N=4 SYM theory by a dimension eight chiral operator. The calculation does not depend on how the theory is regularized. This result provides another hint that holographic duality between the D3-brane worldvolume theory and the corresponding supergravity solution may be valid beyond the near horizon limit.
