论文摘要
我们研究了适用于适合低Momentum量表应用的制成品夸克式式表示，调查了轻度有效的汉密尔顿的特征性的PART顿分布函数（PDF）和KAON。通过将这些量表作为唯一的自由参数，QCD演变后的价夸克分布函数与Fermilab的E615实验一致。此外，KAON中的UP夸克分布与Pion中的夸克分布的比率也与CERN的Na3实验结果一致。
We investigate the parton distribution functions (PDFs) of the pion and kaon from the eigenstates of a light-front effective Hamiltonian in the constituent quark-antiquark representation suitable for low-momentum scale applications. By taking these scales as the only free parameters, the valence quark distribution functions of the pion, after QCD evolving, are consistent with the E615 experiment at Fermilab. In addition, the ratio of the up quark distribution in the kaon to that in the pion also agrees with the NA3 experimental result at CERN.
