Flavor Symmetry of Quarks/Leptons and its Verification

点击翻译按钮获取中文摘要

In this project, we study the phenomenological consequences in the framework of the non-abelian discrete flavor symmetry. At first, we predict the large two neutrino mixing angles and the reactor angle by using the flavor symmetry. Based on this result, we clarify the flavor structure of the squark and slepton (SUSY particle) as well as quarks/leptons.1. The reactor angle theta_13 is predictable in the A4 and S4 flavor symmetries.2. We present the analyses of the CP violation of B mesons observed at LHCb. In conclusion, we obtain the flavor structure of squarks.
