| Publication Abstract: | We extend our proof of the multiplicative renormalizability of quasi-quark PDFs in Ref.~\cite{Ishikawa:2017faj} to quasi-gluon PDFs, and demonstrated that quasi-gluon PDFs can be multiplicatively renormalized to all orders in perturbation theory, without mixing with other operators. We find that using a gauge-invariant UV regulator is essential for achieving this proof. With the multiplicative renormalizability of both quasi-quark and quasi-gluon PDFs, and QCD collinear factorization of quasi-PDFs into PDFs, we have now a solid theoretical foundation for extracting PDFs from lattice QCD calculated quasi-PDFs. |
