Description

Basis Light-front Quantization (BLFQ) has been proposed as a nonperturbative framework for solving quantum field theory. Based on the resulting light-front wave function obtained within the BLFQ framework, we investigate the several aspects of the nucleon properties such as electromagnetic form factors, generalized parton distributions (GPDs) etc.. In the effective Hamiltonian, we implement a confining potential in the transverse direction inspired by the light-front holography as well as a longitudinal confinement potential for the completeness. The one-gluon exchange interaction has also been included in the effective Hamiltonian for generating the spin structure. The obtained results in BLFQ formalism are compared with the light-front quark-diquark model constructed from the soft-wall AdS/QCD prediction.
