Chiral symmetry breaking in the AdS/CFT correspondence
Jacques Distler1 and Frederic Zamora1
Show affiliationsWe study the SU(3)-invariant relevant deformation of D = 4 
= 4 SU(N) gauge theory at large N using the AdS/CFT correspondence. At low energies, we obtain a non-supersymmetric gauge theory with three left-handed quarks in the adjoint of SU(N). In terms of the five-dimensional gauged supergravity, there is an unstable critical point in the scalar potential for fluctuations of some fields in a non-trivial representation of the symmetry group SU(3). On the field theory side, this corresponds to dynamical breaking of the SU(3) chiral symmetry down to SO(3). We compute the condensate of the quark bilinear and the two-point correlation function of the spontaneously broken currents from supergravity and find a non-zero ``pion'' decay constant, fπ.
