Assessing a candidate IIA dual to metastable supersymmetry-breaking    [PDF]

Gregory Giecold, Enrico Goi, Francesco Orsi

We analyze the space of linearized non-supersymmetric deformations around a
IIA solution found by Cvetic, Gibbons, Lu and Pope (CGLP) in hep-th/0101096. We
impose boundary conditions aimed at singling out among those perturbations
those describing the backreaction of anti-D2 branes on the CGLP background. The
corresponding supergravity solution is a would-be dual to a metastable
supersymmetry-breaking state. However, it turns out that this candidate bulk
solution is inevitably riddled with IR divergences of its flux densities and
action, whose physical meaning and implications for models of string cosmology
call for further investigation.
