Torus shadow formalism and exact global conformal blocks

open access: yesJournal of High Energy Physics, 2023
Using the shadow formalism we find global conformal blocks of torus CFT2. It is shown that n-point torus blocks in the “necklace” channel (a loop with n legs) are expressed in terms of a hypergeometric-type function which we refer to as the necklace ...
