Matter matters in moduli fixing and modular flavor symmetries

Modular flavor symmetries provide us with a very compelling approach to the flavor problem. It has been argued that moduli values close to some special values like τ=i or τ=ω provide us with the best fits to data. We point out that the presence of hidden “matter” fields, needed to uplift symmetric A...

Description
Summary:Modular flavor symmetries provide us with a very compelling approach to the flavor problem. It has been argued that moduli values close to some special values like τ=i or τ=ω provide us with the best fits to data. We point out that the presence of hidden “matter” fields, needed to uplift symmetric AdS vacua, gives rise to a dynamical mechanism that leads to such values of τ.
