Abstract I will review recent results from the JAM Collaboration on pion and kaon parton distribution functions (PDFs) obtained from global QCD analysis of experimental Drell-Yan and leading neutron electroproduction data, together with lattice QCD calculations
of PDF moments and Ioffe time distributions. The analysis indicates a softer valence up-quark distribution in the K+ compared with the ð+, and provides the first empirical evidence for significantly different valence up and anti-strange densities in the kaon.
Inclusion of recent lattice calculations of gluonic pseudo Ioffe-time distributions also significantly reduces uncertainties on the gluon PDF, revealing a higher gluon density in the pion at large momentum fractions than in the proton.</div>
