The many faces of brane-flux annihilation
The many faces of brane-flux annihilation
Fluxes can decay via the nucleation of Brown-Teitelboim bubbles, but whenthe decaying fluxes induce D-brane charges this process must be accompanied with anannihilation of D-branes.

Abstract
Fluxes can decay via the nucleation of Brown-Teitelboim bubbles, but whenthe decaying fluxes induce D-brane charges this process must be accompanied with anannihilation of D-branes. This occurs via dynamics inside the bubble wall as was welldescribed for D3 branes annihilating against 3-form fluxes. In this paper we extend this tothe other Dp branes with p smaller than seven. Generically there are two decay channels:one for the RR flux and one for the NSNS flux. The RR channel is accompanied bybrane annihilation that can be understood from the Dp branes polarising into D(p + 2)branes, whereas the NSNS channel corresponds to Dp branes polarising into NS5 branesor KK5 branes. We illustrate this with the decay of antibranes probing local toroidalthroat geometries obtained from T-duality of the D6 solution in massive type IIA. Weshow that Dp branes are metastable against annihilation in these backgrounds, at least atthe probe level.
