论文摘要
我们报告了$ d^*$和$ d^*_ s $介子及其前四个时刻的纵向和横向灯前分配幅度的首次计算。 As a byproduct, 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.
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 $ρ$, $ϕ$, $K^*$ 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.
