概要

    ABSTRACT

In this talk, we begin by reviewing the basic of CFT correlation functions for operators with spins and the structures of their holographic duals: Spinning Witten Diagrams. I will then talk about so-called "Spinning Geodesic Witten Diagrams" (SGWDs), proposed to be the holographic dual configuration of spinning conformal partial waves, from the perspectives of CFT operator product expansions. To this end, we explicitly consider three point SGWDs which are natural building blocks of all possible four point SGWDs, discuss their gluing procedure through integration over spectral parameter, and this leads us to a direct identification with the integral representation of CFT conformal partial waves. If the time allows, I will also wrap up the seminar with some on-going work for construct so-called Mellin amplitudes for spinning fields. The contents of this talk will be based on work collaborated with En-Jui Kuo and Hideki Kyono.
