摘要
We consider the dynamics of p anti-D3 branes inside the Klebanov-Strassler geometry, the deformed conifold with M units of RR 3-form flux around the S-3. We find that for p<<M the system relaxes to nonsupersymmetric NS 5-brane "giant graviton" configuration, which is classically stable, but quantum mechanically can tunnel to nearby supersymmetric vacuum with M-p D3 branes. This decay mode is exponentially suppressed and proceeds via the nucleation of an NS 5-brane bubble wall. We propose dual field theory interpretation of the decay as the transition between nonsupersymmetric "baryonic" branch and supersymmetric "mesonic" branch of the corresponding SU(2M-p) x SU(M-p) low energy gauge theory. The NS 5-brane tunneling process also provides simple visualization of the geometric transition by which D3-branes can dissolve into 3-form flux.
