摘要

在大动量有效理论的框架下，利用HYP涂抹价三叶草夸克的混合作用方法，对介子内部的部分子分布进行了初步研究。我们使用2+1 flavor $48^3 \乘以64$ HISQ晶格，晶格间距为a=0.06 fm，价夸克质量对应于介子质量为300 MeV。

Pion structure from lattice QCD

We present preliminary study of parton distribution inside the pion using mixed action approach with HYP smeared valence clover quarks on HISQ sea within the framework of Large Momentum Effective Theory. We use 2+1 flavor $48^3 \times 64$ HISQ lattices with lattices spacing of a=0.06 fm and valence quark masses corresponding to pion mass of 300 MeV.
