Conformal field theories are non-trivial fixed points of quantum field theories. For the subclass of superconformal field theories (SCFTs) in dimension D>3, it is hoped that all of them can be constructed from parent 6D SCFTs. In this talk, I'm going to present our new tool kit to classify and study 5D N=1 SCFTs along this approach. Namely, each strongly coupled 5D N=1 SCFT is associated with a graph, which is called "combined fiber diagram". It explicitly contains the information about the flavor symmetry, BPS states, and transitions between different SCFTs. With this powerful tool, one can simply read off the enhanced flavor symmetry of a 5D N=1 gauge theory at its UV fixed point, which is very difficult to compute with other methods. 王一男于2009年至2013年就读于北京大学物理学院，毕业以后赴美国麻省理工学院物理系攻读博士学位。在Washington Taylor教授指导下，王一男于2018年博士毕业，之后在牛津大学数学系数学物理组做博士后。目前的主要研究方向是弦论，超对称量子场论以及理论物理中的代数几何方法。
