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 …
Symmetry Enhancements in 7d Heterotic Strings
Bernardo Fraiman, Héctor Parra De Freitas
We use a moduli space exploration algorithm to produce a complete list of maximally enhanced gauge groups that are realized in the heterotic string in 7d, encompassing the usual Na…
Exploring the landscape of CHL strings on T^d
Anamaria Font, Bernardo Fraiman, Mariana Graña +2
Compactifications of the heterotic string on special T^d/Z_2 orbifolds realize a landscape of string models with 16 supercharges and a gauge group on the left-moving sector of redu…
