Abstract

We report on the first calculation of the longitudinal and transverse light front distribution amplitudes of the D* and Ds* mesons and their first four moments. As a by-product, we also obtain these distribution amplitudes for the ρ, ϕ, K*, and J/Ψ 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.
