Non-supersymmetric heterotic strings and chiral CFTs
Hector Parra De Freitas
Non-supersymmetric heterotic strings share various properties with their supersymmetric counterparts. Torus compactifications of the latter live in a component of the moduli space…
Affine Algebras at Infinite Distance Limits in the Heterotic String
Veronica Collazuol, Mariana Graña, Alvaro Herráez +1
We analyze the boundaries of the moduli spaces of compactifications of the heterotic string on , making particular emphasis on and its F-theory dual. We compute the OPE…
New Supersymmetric String Moduli Spaces from Frozen Singularities
Héctor Parra De Freitas
The current classification of string theories in eight and seven dimensions is completely captured by K3 surfaces with F-Theory or M-Theory frozen singularities.…
Freezing of Gauge Symmetries in the Heterotic String on
Bernardo Fraiman, Héctor Parra de Freitas
We derive a map relating the gauge symmetry groups of heterotic strings on to other components of the moduli space with rank reduction. This generalizes the results for …
