Stringy Gauge Structures
Gerardo Aldazabal, Eduardo Andrés, Lucía M. Cabrera +1
A field theory action, able to incorporate stringy gauge symmetry enhancement-breaking effects, which occur at particular points of moduli space in a heterotic string toroidal comp…
Heterotic Strings on , 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 , without supersymmetry…
Stringy Tachyonic Instabilities of Non-Supersymmetric Ricci Flat Backgrounds
Bobby Samir Acharya, Gerardo Aldazabal, Eduardo Andrés +3
Superstring/M-theory compactified on compact Ricci flat manifolds have recently been conjectured to exhibit instabilities whenever the metrics do not have special holonomy. We use…
Symmetry enhancement interpolation, non-commutativity and Double Field Theory
G. Aldazabal, E. Andrés, M. Mayo +1
We present a moduli dependent target space effective field theory action for (truncated) heterotic string toroidal compactifications. When moving continuously along moduli space, t…
A Note on 4D Heterotic String Vacua, FI-terms and the Swampland
Gerardo Aldazabal, Luis E. Ibáñez
We present a conjecture for the massless sector of perturbative 4D heterotic string vacua, including gauge symmetries,one of them possibly anomalous (like in…
Double Field Theory description of Heterotic gauge symmetry enhancing-breaking
Gerardo Aldazabal, Eduardo Andres, Martin Mayo +1
A Double Field Theory (DFT) description of gauge symmetry enhancing-breaking in the heterotic string is presented. The construction, based on previous results for the bosonic strin…
