  We investigate the tomographical structure of pion and kaon in light cone
quark model (LCQM). In particular, we study the parton distribution amplitude
(PDA) of pion and kaon. We obtain the parton distribution function (PDF) and
the generalized parton distributions (GPDs) of the pion and kaon. The valence
quark PDA and PDF of 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 pion
and kaon. We also discuss the unpolarized TMD evolution for pion and kaon in
this model.
