Talk Title: "Twistor methods for superconformal blocks"


Conformal blocks are fundamental ingredients in the CFT bootstrap program. They encapsulate the contribution of a primary operator and all its descendants to a particular four-point function, but computing them is a challenge, especially in supersymmetric CFTs. I will discuss recent efforts using twistors to develop a simplified, covariant framework for computing conformal blocks in four-dimensional CFTs with N-extended supersymmetry. This framework has enabled the computation of new superconformal blocks.
