Abstract: 

  Conformal field theories (CFT) play an important role in our understanding of quantum field theories in general, and description of critical phenomena and physics beyond the Standard Model. In this talk I will introduce a semi-classical approach to computing CFT data that has been developed in recent years, with an emphasis on its novel application to theories with non-Abelian global symmetries and/or complex fixed points.
