Revisiting N=4 superconformal blocks

Understand

We study four-point correlation functions of four generic half-BPS supermultiplets of N=4 SCFT in four dimensions.

• We use the two-particle Casimir of four-dimensional superconformal algebra to derive superconformal blocks which contribute to the partial wave expansion of such correlators.
• The derived blocks are defined on analytic superspace and allow us in principle to find any component of the four-point correlator.
• The lowest component of the result agrees with the superconformal blocks found by Dolan and Osborn.
