abstract
We report on the first calculation of the longitudinal and transverse light front distribution amplitudes of the $D^*$ and $D^*_s$ mesons and their first four moments. As a byproduct, we also obtain these distribution amplitudes for the $\rho$, $\phi$, $K^*$ and $J/\Psi$ mesons and confirm a prediction of lattice QCD for the vector kaon: while the longitudinal distribution amplitude is almost symmetric, the transverse one is oblique implying that the strange quark carries more momentum.

Imaging the charge distributions of flavor-symmetric and -asymmetric mesons
Using a maximum-entropy inversion of DSE/BSE form factors, the authors map meson charge profiles and find quark-antiquark distances that shrink with quark mass and grow by 5-15% for spin-aligned mesons.

Vector mesons leading-twist longitudinal distribution amplitudes and related semi-leptonic decays within QCD sum rules
New QCD sum-rule calculation gives ξ-moments up to tenth order and PLP-model distribution amplitudes for ρ, K*, φ, which are then used to recalculate D_(s)→V semileptonic observables.
