Non-Supersymmetric Vacua and Self-Adjoint Extensions
J. Mourad, A. Sagnotti
Internal intervals spanned by finite ranges of a conformal coordinate and terminating at a pair of singularities are a common feature of many string compactifications with brok…
A 4D IIB Flux Vacuum and Supersymmetry Breaking. I. Fermionic Spectrum
J. Mourad, A. Sagnotti
We consider the type-IIB supergravity vacua that include an internal , depend on a single coordinate and respect a four-dimensional Poincaré symmetry, with the aim of high…
On Warped String Vacuum Profiles and Cosmologies, II. Non-Supersymmetric Strings
J. Mourad, A. Sagnotti
We investigate the effects of the leading tadpole potentials of 10D tachyon-free non-supersymmetric strings in warped products of flat geometries of the type M(p+1) x R x T(10-p-2)…
On Warped String Vacuum Profiles and Cosmologies, I. Supersymmetric Strngs
J. Mourad, A. Sagnotti
We investigate in detail solutions of supergravity that involve warped products of flat geometries of the type M(p+1) x R x T(D-p-2) depending on a single coordinate. In the absenc…
String (In)Stability Issues with Broken Supersymmetry
J. Mourad, A. Sagnotti
We review the main results of our investigations motivated by the tadpole potentials of ten-dimensional strings with broken supersymmetry. While these are at best partial indicatio…
On Boundaries, Charges and Fermi Fields
J. Mourad, A. Sagnotti
We address some general issues related to torsion and Noether currents for Fermi fields in the presence of boundaries, with emphasis on the conditions that guarantee charge conserv…
