Description
We review recent progress in Hamiltonian Light-Front quantization of QCD within a basis function representation known as BLFQ. Expanded Fock spaces are employed to include dynamical gluons and sea quark-antiquark pairs. Observables such as mass spectra, parton distribution functions (PDFs), electromagnetic form factors and transitions, among others, are calculated and compared with experiment where available as well as with other theoretical approaches. Good agreement with experiment is obtained in many cases and residual discrepancies point to a need for larger basis spaces. We also discuss recent progress in accounting for bosonic zero mode contributions within a scalar field theory application.
