Abstract
In this talk, I present our recent work on the data-driven extraction of the unpolarized quark Generalized Parton Distributions (GPDs) of the pion at zero skewness. Using a global fit to experimental pion electromagnetic form factor and PDF data, we determine the pion GPDs through a flexible parameterization embedded in a GPD framework with collinear PDFs and a profile function encoding transverse dynamics. Impact-parameter-space interpretations of the spatial parton distributions are discussed, revealing the internal structure of the lightest QCD bound state. The results provide essential input for future experiments at EIC, JLab 12 GeV, COMPASS, and AMBER.
