| Title | Double distributions and pseudodistributions | ||||
| Abstract | We describe an approach of lattice extraction of Generalized Parton Distributions that is based on use of the double distributions (DDs) formalism within the pseudo-distribution approach. The advantage of using DDs is hat GPDs obtained in this way have the mandatory polynomiality property, a non-trivial correlation between $x$- and $\xi$-dependences of GPDs. Another advantage of using DDs is that the $D$-term appears as an independent quantity in the DD formalism rather than part of GPDs $H$ and $E$. We relate the $\xi$-dependence of GPDs to the width of the $\alpha$-profiles of the corresponding DDs, and discuss strategies for fitting lattice-extracted pseudo-distributions by DDs. The approach described in the present paper may be used in ongoing and future lattice extractions of GPDs. | ||||
