摘要：

We investigate the tomographical structure of the pion and kaon in the light-cone quark model. In particular, we study the parton distribution amplitude (PDA) of the pion and kaon. We obtain the parton distribution function (PDF) and the generalized parton distributions of the pion and kaon. The valence quark PDA and PDF of the pion, after QCD evolution, are found to be consistent with the data from the E791 and the E615 experiments at Fermilab, respectively. Further, we investigate the transverse momentum distributions (TMDs) of the pion and kaon. We also discuss the unpolarized TMD evolution for the pion and kaon in this model.
