Abstract摘要

Modular symmetry is a new approach to address the flavor puzzle of the Standard Model (SM). This approach can overcome the drawbacks of traditional flavor symmetry, and it allows to explain the observed fermion masses and mixing parameters with a small number of free parameters. In this series of lectures, I will give a pedagogical introduction to the modular symmetry and its application to flavor physics. The basic ideas and techniques will be explained, and the extension of modular symmetry to the double cover and metaplectic cover, the generalized CP symmetry and multiple moduli will be discussed. Some typical predictive modular models as well as the phenomenological predictions will be presented. Finally I give an introduction to the grand unification theory in the context of modular symmetry.

Curriculum Vitae：

Gui-Jun Ding obtained the PhD degree in 2007 from University of Science and Technology of China, then continue to work in the same university as a postdoctoral research fellow from 2007 to 2009, as a faculty since 2009. At present, his research interest is in the fermion mass models, modular flavor symmetry and neutrinoless double decay.
