论文摘要
我们研究了光锥模型（LCQM）中暂停和kaon的层合结构。特别是，我们研究了Pion和Kaon的Parton分布幅度（PDA）。我们获得了Parton分布函数（PDF）和PION和KAON的广义Parton分布（GPD）。发现QCD演化后的价夸克PDA和PDF分别与Fermilab的E791和E615实验的数据一致。此外，我们研究了Pion和Kaon的横向动量分布（TMD）。我们还讨论了该模型中乳子和KAON的非偏振TMD演变。
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.
