Torus shadow formalism and exact global conformal blocks

High Energy Physics - Theory 2023-07-25 v1

Abstract

Using the shadow formalism we find global conformal blocks of torus CFT2_2. It is shown that nn-point torus blocks in the ``necklace'' channel (a loop with nn legs) are expressed in terms of a hypergeometric-type function which we refer to as the necklace function.
