| Publication Abstract: | We complete the procedure of extracting parton distribution functions (PDFs) using large momentum effective theory (LaMET) at leading power accuracy in the hadron momentum. We derive a general factorization formula for the quasi parton distribution functions in the presence of mixing, and give the corresponding hard matching kernel both for the unpolarized and for the polarized quark and gluon quasi-PDFs at $\mathcal O(\alpha_s)$. Our calculation is performed in a regularization-independent momentum subtraction scheme. The results allow us to match the nonperturbatively renormalized quasi-PDFs to normal PDFs in the presence of mixing, and therefore can be used to extract flavor-singlet quark PDFs as well as the gluon PDFs from lattice simulations. |
