We investigate the tomographical structure of pion and kaon in light cone quark model (LCQM). In particular, we study the parton distribution amplitude (PDA) of pion and kaon. We obtain the parton distribution function (PDF) and the generalized parton distributions (GPDs) of the pion and kaon. The valence quark PDA and PDF of pion, after QCD evolution, are found to be consistent with the data from the E791 and the E615 experiments at Fermilab, respectively. Further, we investigate the transverse momentum distributions (TMDs) of pion and kaon. We also discuss the unpolarized TMD evolution for pion and kaon in this model.

  1. Strange mesons with one dynamical gluon: A light-front approach

    hep-ph 2025-01 conditional novelty 5.0 of 10

    A basis light-front QCD model with one dynamical gluon reproduces strange meson spectra and yields kaon form factors, PDFs, and Drell-Yan cross sections testable at COMPASS++/AMBER.
