Brane/flux annihilation and the string dual of a nonsupersymmetric field theory
Abstract
We consider the dynamics of p antiD3 branes inside the KlebanovStrassler geometry, the deformed conifold with M units of RR 3form flux around the S^{3}. We find that for p << M the system relaxes to a nonsupersymmetric NS 5brane `giant graviton' configuration, which is classically stable, but quantum mechanically can tunnel to a nearby supersymmetric vacuum with Mp D3 branes. This decay mode is exponentially suppressed and proceeds via the nucleation of an NS 5brane bubble wall. We propose a dual field theory interpretation of the decay as the transition between a nonsupersymmetric `baryonic' branch and a supersymmetric `mesonic' branch of the corresponding SU(2Mp) × SU(Mp) low energy gauge theory. The NS 5brane tunneling process also provides a simple visualization of the geometric transition by which D3branes can dissolve into 3form flux.
