A gravity dual of chiral symmetry breaking

Abstract

AbstractWe establish a holographic description of chiral symmetry breaking for a particular confining large N non‐supersymmetric gauge theory with matter in the fundamental representation. The gravity dual of this theory is obtained by introducing a D7‐brane probe into a deformed Anti‐de Sitter background found by Constable and Myers. We numerically compute the $\bar\psi\psi$ condensate and meson spectrum by solving the equation of motion of the D7‐brane probe in this background. We find a symmetry breaking condensate as well as the associated, pion‐like, Goldstone boson in the limit of small quark mass. The existence of the condensate ensures that the D7‐brane never reaches the naked singularity at the origin of the deformed AdS space.
