Unpolarized isovector GPDs from lattice QCD in the pseudo-distribution formalism

We provide a reconstruction of the (x, xi, t) dependence of the proton's unpolarized isovector generalized parton distributions (GPDs) from lattice QCD at a pion mass of 358 MeV and a lattice spacing of 0.094 fm, matched with leading logarithmic accuracy to mu = 2 GeV. This dataset is associated to the publication "Reconstructing the full kinematic dependence of GPDs from pseudo-distributions" available at arXiv:2604.21476. For the first time in the literature, the GPDs are computed from lattice data using the double distribution formalism that guarantees the respect of the polynomiality property. The regularization of the inverse problem is performed thanks to a multidimensional Gaussian process regression, offering a large flexibility and an assessment of model dependence. The results are provided at 8 values of the invariant momentum transfer t spanning [0, -1.4] GeV^2, 5 values of the skewness xi spanning [0, 1] and 100 values of x spanning [0, 1].
