Description
Basis Light-Front Quantization (BLFQ) is a fully relativistic and nonperturbative framework for solving the light-front QCD Hamiltonian, aiming at first-principles calculations of hadron structure.
For the nucleon system, we extend the Fock space up to six-particle sectors, including configurations such as five-quark–one-gluon and three-quark–three-gluon components with dynamical gluons. In our calculations, we implement the full light-front QCD Hamiltonian without introducing any effective interactions.
By fitting the nucleon and Λ mass spectra together with their electromagnetic form factors within a truncated basis space, we constrain the remaining model parameters. Diagonalization of the QCD Hamiltonian yields light-front wave functions that preserve the symmetry properties of fermions and gluons.
Using these wave functions, we compute physical observables such as gluon and sea-quark parton distribution functions (PDFs) at a low resolution scale. The resulting distributions are subsequently evolved to higher momentum scales via QCD evolution for direct comparison with experimental measurements.
Finally, we outline future prospects and ongoing developments of this framework.
