Massive spin 2 excitations in AdS6 × S2 warped spacetimes

Abstract

We study (massive) spin-2 fluctuations around warped AdS6 solutions with 16 supersymmetries in type IIB supergravity. We identify two classes of fluctuations which are universally present for all solutions of this form. The holographically dual operators have scaling dimensions ∆ = 5 + 3` and ∆ = 6 + 3`, where the integer ` encodes the R-symmetry charge. They are identified as descendant states in respective BPS multiplets (the current multiplet for ∆ = 5). We also compute the normalization of the energy-momentum tensor two-point function and show that it is related to the S 5 partition function of the dual 5d SCFTsThe work of MG and CFU is supported in part by the National Science Foundation under grant PHY- 16-19926.
