Heterotic Strings on ${\mathbb{T}}^3/{\mathbb{Z}}_2$, Nikulin involutions and M-theory

Bobby Samir Acharya, Gerardo Aldazabal, Anamaría Font +2

We first describe the low energy dynamics of ten dimensional heterotic supergravity compactified on the smooth, flat 3-manifold ${\mathbb{T}}^3/{\mathbb{Z}}_2$, without supersymmetry…
