Kaluza-Klein spectroscopy for the Leigh-Strassler SCFT

We apply recently developed tools from exceptional field theory to calculate the full Kaluza-Klein spectrum of the AdS5 Pilch-Warner solution of type IIB supergravity. Through the AdS/CFT correspondence this yields detailed information about the spectrum of protected and unprotected operators of the four-dimensional N = 1 Leigh-Strassler SCFT, in the planar limit. We also calculate explicitly the superconformal index of the SCFT in this limit and show that it agrees precisely with the spectrum of protected operators in the supergravity calculation.

Researchers utilized recently developed tools from exceptional field theory to calculate the full Kaluza-Klein spectrum of the AdS5 Pilch-Warner solution in type IIB supergravity, providing detailed information about the spectrum of protected and unprotected operators in the four-dimensional N = 1 Leigh-Strassler SCFT through the AdS/CFT correspondence. They also explicitly calculated the superconformal index of the SCFT in this limit and demonstrated its precise agreement with the spectrum of protected operators in the supergravity calculation.
