Since cake seminars are more internal and informal, we wanted to default to not having a call available to everyone on the mailing list. If you desire to call in for whatever reason, please reach out to us and we'll check with the speaker if they are ok with
it.</div>

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>
