Título: | E3-brane instantons and baryonic operators for D3-branes on toric singularities |
Autor: | Forcella, Davide; García-Etxebarria, Iñaki; Uranga Urteaga, Ángel M. | Fecha de publicación: | 13-jun-2008 | Citación: | arXiv:0806.2291v1 [hep-th] | Serie: | IFT-UAM/CSIC-08-36 | Resumen: | We consider the couplings induced on the world-volume field theory of D3-branes at local toric Calabi-Yau singularities by euclidean D3-brane (E3-brane) instantons wrapped on (non-compact) holomorphic 4-cycles. These instantons produce insertions of BPS baryonic or mesonic operators of the four-dimensional ${\cal{N}}=1$ quiver gauge theory. We argue that these systems underlie, via the near-horizon limit, the familiar AdS/CFT map between BPS operators and D3-branes wrapped on supersymmetric 3-cycles on the 5d horizon. The relation implies that there must exist E3-brane instantons with appropriate fermion mode spectrum and couplings, such that their non-perturbative effects on the D3-branes induce operators forming a generating set for all BPS operators of the quiver CFT. We provide a constructive argument for this correspondence, thus supporting the picture. | Descripción: | 41 pages, 13 figures. | URI: | http://hdl.handle.net/10261/5276 |
