Title:   “Modular invariance and the flavor puzzle”

Abstract:

The flavor sector of particle physics requires more than 20 parameters for a complete description. Despite the very precise available data, the
origin of these parameters remains obscure. Such a flavor puzzle is one of the most profound and fascinating problems of fundamental interactions.

The hope of deriving these parameters from a fundamental principle has led scientists to explore a great variety of symmetries patterns. In this talk, I will show how the role of flavor symmetry can be played by modular invariance, ubiquitous in string theory and condensed matter systems. Modular invariance can be explored in a consistent bottom-up
approach, which here will be reviewed and applied to neutrino masses and mixing angles.   Despite the freedom inherent in model building, a set of universal predictions free from ambiguities can be formulated when the theory approaches a critical point, much as in the case of phase transitions. In addition, modular invariance can shed light on one long standing mystery of the quark sector, the strong CP problem.
