Non-abelian family symmetries in Pati-Salam unification

  • Ivo de Medeiros VarzielasEmail author


We present a framework of underlying SU(3)×SU(3) family symmetries consistent with Pati-Salam unification and discuss advantages that can justify introducing multiple non-Abelian factors. Advantages include improved vacuum alignment and increased predictivity. We explore in this framework deviations from tri-bi-maximal neutrinos, such as relatively large θ 13.
