Bootstrapping AdS$_2 \times$ S$^2$ hypermultiplets: hidden four-dimensional conformal symmetry

Published 5 Mar 2024 in hep-th | (2403.03285v3)

Abstract: We bootstrap the $4$-point amplitude of $\mathcal{N}=2$ hypermultiplets in $\text{AdS}_2 \times \text{S}2$ at tree-level and for arbitrary external weights. We hereby explicitly demonstrate the existence of a hidden four-dimensional conformal symmetry that was used as an assumption in previous studies to derive this result.
