Heterotic orbifolds, reduced rank and SO(2n+1) characters
Hervé Partouche, Balthazar de Vaulchier
The moduli space of the maximally supersymmetric heterotic string in d-dimensional Minkowski space contains various components characterized by the rank of the gauge symmetries of…

Induced cosmological and Newton constants from towers of states
Hervé Partouche, Balthazar de Vaulchier
We consider quadratic gravity with only Ricci squared and Weyl squared kinetic terms at tree-level, coupled to specific numbers of infinite towers of free scalars, Weyl fermions an…

Phase transition at high supersymmetry breaking scale in string theory
Herve Partouche, Balthazar de Vaulchier
When supersymmetry is spontaneously broken at tree level, the spectrum of the heterotic string compactified on orbifolds of tori contains an infinite number of potentially tachyoni…
