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 t = i or t = w 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 t.& COPY; 2023 The Author(s).

Automated summary

Modular flavor symmetries offer a compelling solution to the flavor problem. It has been argued that moduli values close to specific values like t = i or t = w provide the best fits to data. The presence of hidden matter fields, necessary to uplift symmetric AdS vacua, leads to a dynamical mechanism that results in such values of t.
