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…
Non-supersymmetric non-tachyonic heterotic vacua with reduced rank in various dimensions
Carlo Angelantonj, Ioannis Florakis, Giorgio Leone +1
We construct rigid non-supersymmetric heterotic vacua with reduced rank and no tachyons in six and four dimensions. These configurations are based on asymmetric orbifold compactifi…
Species scale, worldsheet CFTs and emergent geometry
Christian Aoufia, Ivano Basile, Giorgio Leone
We study infinite-distance limits in the moduli space of perturbative string vacua. The remarkable interplay of string dualities seems to determine a highly non-trivial dichotomy,…
Rigid Vacua with Brane Supersymmetry Breaking
C. Angelantonj, C. Condeescu, E. Dudas +1
We construct new string vacua featuring Brane Supersymmetry Breaking, based on orientifolds with planes and branes. Differen…
