New comments on six-dimensional orientifold vacua with reduced rank and unitarity constraints
Giorgio Leone
We revisit and extend the construction of six-dimensional orientifolds built upon the orbifolds with a non-vanishing Kalb-Ramond background, both in the presence…

Aspects of Stability, Rigidity and Unitarity in String Vacua
Giorgio Leone
In this Thesis we investigate properties of stability, rigidity and unitarity of the string landscape in ten and lower dimensions. The dissertation explores these aspects by intert…

Tachyons and Misaligned Supersymmetry in Orientifold Vacua
Giorgio Leone
We extend the analysis of Misaligned Supersymmetry to orientifold vacua. The lack of modular invariance in the Klein bottle, annulus and Möbius strip amplitudes implies that the IR…
