Abstract

© 2014, Springer Science+Business Media Dordrecht. 3d (Formula Presented.) partition functions on the squashed three-sphere (Formula Presented.) and on the twisted product (Formula Presented.) have been shown to factorize into sums of squares of solid tori partition functions, the so-called holomorphic blocks. The same set of holomorphic blocks realizes (Formula Presented.) and (Formula Presented.) partition functions but the two cases involve different inner products, the S-pairing and the id-pairing, respectively. We define a class of q-deformed CFT correlators where chiral blocks are controlled by a deformation of Virasoro symmetry and are paired by S-pairing and id-pairing, respectively. Applying the bootstrap approach to a class of degenerate correlators we are able to derive three-point functions. We show that degenerate correlators can be mapped to 3d partition functions while the crossing symmetry of correlators corresponds to the flop symmetry of 3d gauge theories. We explore how non-degenerate q-deformed correlators are related to 5d partition functions. We argue that id-pairing correlators are associated with the superconformal index on (Formula Presented.) while S-pairing three-point function factors capture the one-loop part of S5 partition functions. This is consistent with the interpretation of (Formula Presented.) and (Formula Presented.) gauge theories as codimension two defect theories inside (Formula Presented.) and S5, respectively.
