Abstract: Using xFitter, we extract parton distribution functions of charged pions from currently available Drell-Yan and photon production data. While the valence distribution is well-constrained, we find that the considered data are not sensitive enough to unambiguously determine sea and gluon distributions. In the used approximation, we find the high-x behavior of the valence distribution to be linear in (1-x) at high x. Fractions of momentum carried by the valence, sea and gluon components are discussed.
