Description

We obtain the light meson light-front wavefunctions (LFWFs) from the light-front QCD Hamiltonian, determined for their constituent quark-antiquark and quark-antiquark-gluon Fock components, together with a three-dimensional confinement. By fitting the model parameters to achieve the light-meson mass spectroscpy, the LFWFs provide a good quality description of the pion electromagnetic form factor, decay constant, and the valence quark distribution functions following QCD scale evolution. We further employ the LFWFs to compute the gluon PDFs, GPDs and TMDs in the light mesons.
