We show how chiral type I models whose tadpole conditions have no supersymmetric solution can be consistently defined introducing antibranes with non-supersymmetric world volumes. At tree level, the resulting stable non-BPS configurations correspond to tachyon-free spectra, where supersymmetry is broken at the string scale on some (anti)branes but is exact in the bulk, and can be further deformed by the addition of brane-antibrane pairs of the same type. As a result, a scalar potential is generated, that can stabilize some radii of the compact space. This setting has the novel virtue of linking supersymmetry breaking to the consistency requirements of an underlying fundamental theory.

The paper
Original abstract
We show how chiral type I models whose tadpole conditions have no supersymmetric solution can be consistently defined introducing antibranes with non-supersymmetric world volumes. At tree level, the resulting stable non-BPS configurations correspond to tachyon-free spectra, where supersymmetry is broken at the string scale on some (anti)branes but is exact in the bulk, and can be further deformed by the addition of brane-antibrane pairs of the same type. As a result, a scalar potential is generated, that can stabilize some radii of the compact space. This setting has the novel virtue of linking supersymmetry breaking to the consistency requirements of an underlying fundamental theory.

In cases where this extra ingredient breaks supersymmetry i.e. is an anti-string (see [ref] , also [ref] for similar phenomena in higher dimensions), this is reminiscent of the antibrane uplift in [ref] .

In this section we investigate the low-energy physics of the string models that we have described in Section [ref], namely the non-supersymmetric $SO(16) ×SO(16)$ heterotic model [ref] , whose first quantum correction generates a dilaton potential, and two orientifold models, the non-supersymmetric $U(32)$ type $0'B$ model [ref] and the $USp(32)$ model [ref] with “Brane Supersymmetry Breaking” (BSB) [ref] , where a similar potential reflects the tension unbalance present in the vacuum.
