要旨:
We study (massive) spin-2 fluctuations around warped $AdS_6$ 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 $\Delta=5+3\ell$ and
$\Delta=6+3\ell$, where the integer $\ell$ encodes the $R$-symmetry charge.
They are identified as descendant states in respective BPS multiplets (the
current multiplet for $\Delta=5$). 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 $5d$ SCFTs.
