Description

We present a self-consistent light-front quark model for the pion and kaon based on the Bakamjian--Thomas (BT) construction and study their electromagnetic form factors,
unpolarized T-even transverse-momentum-dependent distributions (TMDs), and collinear parton distribution functions (PDFs). A consistent implementation of the invariant
mass $M_0$ in both hadronic matrix elements and Lorentz structures enforces four-momentum conservation and yields current-component--independent observables.
The light-front zero-mode issue and its resolution in TMD and form factor calculations are also discussed. We further analyze the perturbative QCD evolution of the valence PDFs.
