Description
I will give an introduction to modular symmetries and how
they can be interpreted as a family symmetry. Afterwards, I
will focus on an SU(5) model in 6d where the two extra dimensions are
compactified on a T_2/Z_2 orbifold, with a twist angle of \omega=ei2pi/3. Such construction suggests an underlying modular A_4 symmetry,leading to an effective \mu-\tau reflection symmetry at low energies.
This implies maximal atmospheric mixing and maximal leptonic CP violation.
