Meson structure in light-front holographic QCD

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 $J\mathrm{/}\psi$ mesons and photon-to-meson transition form factors for $\pi$, $\eta$, and ${\eta }^{\mathrm{\prime }}$ mesons. The results are compared with the experimental data, wherever available.
