D* and Ds* distribution amplitudes from Bethe-Salpeter wave functions

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 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.

Automated summary

We present the first calculation of the longitudinal and transverse light front distribution amplitudes for D* and Ds* mesons, as well as their first four moments. Additionally, we obtain these distribution amplitudes for rho, phi, K*, and J/Psi mesons, confirming a lattice QCD prediction regarding the vector kaon: the longitudinal distribution amplitude is nearly symmetric, while the transverse one is oblique, indicating a higher momentum carried by the strange quark.
