Abstract

We discuss the processes of brane bubble nucleation induced by the external branes. The quasiclassical solution for the nucleation by the single external brane has been found in the case when the brane junctions are possible. Exponential factor in the production rate has been calculated. The process induced by the fundamental or D string in the background of two D3 branes is analyzed and its interpretation from the D3 worldvolume theory viewpoint is described.
