This paper studies meson structures using light-front holographic QCD with massive quarks, calculating wave functions, distribution amplitudes, and form factors for various mesons, and compares results with experimental data.

Contribution

It introduces modifications to light-front holographic QCD to include massive quarks and applies it to compute properties of multiple mesons.

Findings

Wave functions and form factors agree with experimental data

Distribution amplitudes are consistent with theoretical expectations

Provides a unified framework for meson analysis in holographic QCD

Abstract

We consider the light-front holographic QCD with the light-front wave functions for mesons, modified for massive quarks. We evaluate the wave functions, distribution amplitudes, and form factors for $\pi$, $\rho$, $K$, and $J/\psi$ mesons and photon-to-meson transition form factors for $\pi$, $\eta$, and $\eta^\prime$ mesons. The results are compared with the experimental data, wherever available.
