Abstract The tachyon-free nonsupersymmetric string theories in ten dimensions have dilaton tadpoles which forbid a Minkowski vacuum. We determine the maximally symmetric backgrounds for the USp (32) Type I string and the SO (16)× SO (16) heterotic string. The static solutions exhibit nine dimensional Poincare symmetry and have finite 9D Planck and Yang–Mills constants. The low energy geometry is given by a ten dimensional manifold with two boundaries separated by a finite distance which suggests a spontaneous compactification of the ten dimensional string theory.

In view of this situation two different attitudes have been taken. It is fair to say that none”
- Type-I strings on magnetised orbifolds and brane transmutation (2000, background): “, although of run-away type for the dilaton, can in some cases stabilise some geometric moduli [15]. Their presence requires a background redefinition [33], that was recently constructed explicitly in [34] for the model in [35]. In general, these vacua correspond to supergravity models frozen in phas”
- The Standard Model from stable intersecting brane world orbifolds (2001, background): “Moreover, in the non-supersymmetric type I string theory discussed in [35,36] the phenomenon of spontaneous compactification occurred due to the NSNS tadpoles.”
- Type I Strings with F- and B-Flux (2000, background): “Another general feature of all the non-supersymmetric vacua is, that there remains an uncancelled NSNS tadpole which leads to a shift in the background, as shown in [16].”
- Four-dimensional string compactifications with D-branes, orientifolds and fluxes (2006, background): “It could for instance be countered by other terms in the action which depend on Φ, or by a space-dependent profile for the background of Φ [136, 137, 138, 139].”
- Inflationary scenarios from branes at angles (2001, background): “Also, since the configuration is non-supersymmetric, there are uncancelled NSNS tadpoles that should be taken into account [22, 23, 24, 25].”
