We compute the t-dependent parton distribution function of valence quarks in a ?c-meson. After reviewing the main ideas behind the pseudo-distribution formalism, and relying on the analytic structure of Ioffe-time distributions, we come up with a proposal for a model-independent extraction of t-dependent parton distribution functions. We present results for the ?c-meson Ioffe time valence t-dependent parton distribution function at a renormalization scale of 3 GeV.
