Non-supersymmetric dualities beyond the gauge algebra
Bernardo Fraiman, Vittorio Larotonda, Ling Lin +1
We provide a testing ground for dualities of non-supersymmetric type 0 orientifolds by finding the global forms of their gauge groups. As an example, we consider the Bergman--Gaber…
Heterotic Ouroboros
Chiara Altavista, Salvatore Raucci, Angel M. Uranga +1
M-theory on has recently been proposed to yield, via quotients, ten-dimensional non-supersymmetric string theories. We revisit the construction t…
Alice in Warpland: KK modes, Warped Compactifications and the Swampland
Salvatore Raucci, Ignacio Ruiz, Irene Valenzuela
We investigate the asymptotic behavior of Kaluza-Klein (KK) towers in warped compactifications to Minkowski space. Focusing on the overall decompactification limit, we derive the s…
Aspects of strings without spacetime supersymmetry
Giorgio Leone, Salvatore Raucci
String theory relies on spacetime supersymmetry to guarantee the existence of stable vacua. In this review, we survey two features of non-supersymmetric strings that challenge both…
HoÅava-Witten theory on as type 0 orientifold
Chiara Altavista, Edoardo Anastasi, Salvatore Raucci +2
We investigate dualities between quotients of recently proposed compactifications of M-theory on `quantum geometries' of the form ${\mathbf{S}}^1\vee{\mathbf{S}}^1…
AdS vacua of non-supersymmetric strings
Salvatore Raucci, Alessandro Tomasiello
Few vacua are known for the three tachyon-free non-supersymmetric string theories. We find new classes of AdS backgrounds by focusing on spaces where the equations of motion reduce…
