Description
Modular flavor symmetries are realized in string theory. These symmetries act on KK and winding modes. We show that winding modes (i) are key for the interpretation of modular flavor symmetries, (ii) are gauge fields responsible for conventional flavor symmetries, (iii) have different subsets become massless at different critical values of the modulus, and (iv) play an interesting role in CP violation.
