Query: Matching Quasi Generalized Parton Distributions in the RI/MOM scheme   Within the framework of large momentum effective theory (LaMET),
genenaralized parton distributions (GPDs) can be extracted from lattice
calculations of quasi-GPDs through a perturbative matching relation, up to
power corrections that are suppressed by the hadron momentum. In this paper, we
focus on isovector quark GPDs, including the unpolarized, longitudinally and
transversely polarized cases, and present the one-loop matching that connects
the quasi-GPDs renormalized in a regularization-independent momentum
subtraction (RI/MOM) scheme to the GPDs in MS scheme. We find that the matching
coefficient is independent of the momentum transfer squared. As a consequence,
the matching for the quasi-GPD with zero skewness is the same as that for the
quasi-PDF. Our results provide a crucial input for the determination of quark
GPDs from lattice QCD using LaMET.
