Gravitational form factors of vector mesons from top-down approach of holographic QCD

Fujii, Daisuke; Iwanaka, Akihiro*

The gravitational form factors of hadrons are form factors that characterize the matrix elements of the energy-momentum tensor and contain information on the stress distribution inside hadrons. Recently, the gravitational form factors of nucleons have been experimentally extracted and the extremely anisotropic behavior of the nucleon interior has been revealed. In this presentation, we present a study of the gravitational form factors of vector mesons using the Sakai-Sugimoto model, which is one of the top-down approaches to holographic QCD. We show the relationship between the hadron stability condition imposed on the forward limit of the gravitational form factors and the glueball spectra.
