Generalized Parton Distributions of proton for non zero skewness in transverse and longitudinal position spaces

We investigate the Generalized Parton Distributions(GPDs) of proton by expressing them in terms of overlaps of light front wave functions (LFWFs) using a simulated model which is able to qualitatively improve the convergence near the end points of $x$. We study the spin non-flip $H(x, ζ, t)$ and spin flip $E(x, ζ, t)$ part of GPDs for the particle conserving $n \rightarrow n$ overlap in the DGLAP region $(ζ<x<1)$. The Fourier transform (FT) of the GPDs w.r.t. to the transverse momentum transfer as well the FT of the GPDs w.r.t. $ζ$ have also been obtained giving the distribution of partons in the transverse position space and the distribution in the longitudinal position space respectively. Diffraction pattern is obtained for both $\mathcal{H}(x,σ,t)$ and $\mathcal{E}(x,σ,t)$ in the longitudinal position space.
