DBI in the IR

Luca Mezincescu & Paul Townsend
The Infra-Red limit of a planar static D3-brane in AdS5xS5 is a tensionless D3-brane at the Anti-de Sitter horizon with dynamics governed by a strong-field limit of the Dirac-Born-Infeld action, analogous to that found from the Born-Infeld action by Bialynicki-Birula. As in that case, the field equations are those of an interacting 4D conformal invariant field theory with an Sl(2;R) electromagnetic duality invariance, but the D3-brane origin makes these properties manifest. We also find an...
