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

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 t hese corrections, computed previously via supergravity, can be reproduced e xactly in a worldvolume calculation using a deformation of N = 4 SYM theory by a dimension eight chiral operator. The calculation does not depend on h ow the theory is regularized. This result provides another hint that hologr aphic duality between the D3-brane worldvolume theory and the corresponding supergravity solution may be valid beyond the near horizon limit.
