Charting the flavor landscape of MSSM-like Abelian heterotic orbifolds

Understand

Discovering a selection principle and the origin of flavor symmetries from an ultraviolet completion of particle physics is an interesting open task.

• As a step in this direction, we classify all possible flavor symmetries of 4D massless spectra emerging from supersymmetric Abelian orbifold compactifications, including roto-translations and non-factorizable compact spaces, for generic moduli values.
• Although these symmetries are valid in all string theories, we focus on the E8 x E8 heterotic string.
• We perform the widest known search of E8 x E8 Abelian orbifold compactifications, yielding over 121,000 models with MSSM-like features.
