TL;DR
The paper applies supersymmetric localization to compute the exact $S^5$ partition functions of large $N$ five-dimensional SCFTs with $AdS_6$ gravity duals. Localization is performed in IR YM–matter deformations and the resulting free energy is matched to a holographic entanglement-entropy computation in the AdS$_6$ background, reproducing the $F \sim - c N^{5/2}$ scaling. For USp(2N) theories and $Z_n$ orbifolds, explicit large-$N$ saddle densities yield closed forms $F \approx - (9 \sqrt{2} \pi /5) N^{5/2} / \sqrt{8-N_f}$ and $F \approx - (9 \sqrt{2} \pi n^{3/2} N^{5/2}) / (5 \sqrt{8-N_f})$, respectively. The gravity analysis confirms the field-theory results by computing the entanglement entropy across a 3-sphere in the $AdS_6$ background, aligning the universal part with the field-theory $S^5$ free energy and reinforcing the holographic picture for five-dimensional SCFTs.
Abstract
We apply the technique of supersymmetric localization to exactly compute the $S^5$ partition function of several large $N$ superconformal field theories in five dimensions that have $AdS_6$ duals in massive type IIA supergravity. The localization computations are performed in the non-renormalizable effective field theories obtained through relevant deformations of the UV superconformal field theories. We compare the $S^5$ free energy to a holographic computation of entanglement entropy in the $AdS_6$ duals and find perfect agreement. In particular, we reproduce the $N^{5/2}$ scaling of the $S^5$ free energy that was expected from supergravity.
