In this study, we employ a modified soft-wall holographic model with four flavors to
investigate the meson spectra, decay constants, electromagnetic form factors, and charge …

mesons semileptonic form factors in four-flavor holographic QCD

HA Ahmed, Y Chen, M Huang - Physical Review D, 2024 - APS
We investigate semileptonic form factors of a D (s) meson from a modified soft-wall 4-flavor
holographic model. The model successfully reproduces the masses and decay constants of …

Towards a theory of bottom-up holographic models for linear Regge trajectories of light mesons
