We report on the first calculation of the longitudinal and transverse light
front distribution amplitudes of the Dβ and Dsββ mesons and their first
four moments. As a byproduct, we also obtain these distribution amplitudes for
the Ο, Ο, Kβ and J/Ξ¨ 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.Comment: 7 pages, 4 figures, 3 table
