“…We take α(l s ) = α(0) and find λ ∼ g s p, consistent with the estimates in [47]. One can only consistently take α(l s ) = α(0) if α (0) is sufficiently small but this is easy to see.…”

“…This increase in flux diverges close to the antibranes at the classical level. Hence we followed the procedure of [47,48], which amounts to cutting off the singularity at string scale. The main observation is that the cut-off value for the flux density is still too high and causes immediate brane-flux decay.…”

“…The flux-clumping for unpolarised Dk-branes can be inferred either via the supergravity techniques of [21,22] or the brane effective field theory techniques of [47]. Both give the same result, namely…”

“…For the special case p = 1 some initial steps towards a direct effective field theory approach were taken in [47] based on field theory renormalisation [48]. In what follows we will use an alternative description (see for instance [24]).…”

“…This then implies that for large g s p, where we can trust supergravity at that scale, the system is destabilised independent of the ratio p/M being very small. The argument for using the string scale to cut-off can be found in [47,48]. Supergravity should not receive large corrections beyond that scale since for D6 branes in flat space the curvature scales are small enough already at that length scale.…”

We investigate p D6 branes inside a flux throat that carries K × M D6 charges with K the 3-form flux quantum and M the Romans mass. In such a setup brane-flux annihilation can proceed through the nucleation of KK5 branes. We find that within the calculable supergravity regime where g s p is large, the D6 branes annihilate immediately against the fluxes despite the existence of a metastable state at small p/M in the probe approximation. The crucial property that causes this naive conflict with effective field theory is a singularity in the 3-form flux, which we cut off at string scale. Our result explains the absence of regular solutions at finite temperature and suggests there should be a smooth time-dependent solution. We also discuss the qualitative differences between D6 branes and D3 branes, which makes it a priori not obvious to conclude the same instability for D3 branes.

Supersymmetry‐breaking is a key ingredient for string theory models to be phenomenologically viable. We review the strong analogy in the physics and methods used for describing non‐supersymmetric flux vacua and non‐supersymmetric black holes in string theory. We also show how the polarized state could be the key to describing a well‐behaved back‐reaction of anti‐branes in flux backgrounds, shedding a new light on a recent debate in the literature.

We consider flux compactification of type II string theory with local sources on SU(3)‐structure manifolds. By adding pseudo‐calibrated anti‐Dp‐branes wrapped on supersymmetric cycles we generalize all existing models so that the effective d=4, N=1 supergravity now includes a nilpotent multiplet. We present a new dictionary between string theory models and Kähler potential K and superpotential W for these dS supergravities with a nilpotent multiplet and non‐linearly realized local supersymmetry. In addition to KKLT and LVS with uplifting D3¯‐branes, we have now new models with uplifting D5¯, D6¯, D7¯, D9¯‐branes. The new uplifting contribution to the supergravity potential due to Volkov‐Akulov supersymmetry is universal. As one application of our general result, we study classical flux compactifications of type IIA supergravity and find that a previously discovered universal tachyon is now absent.
