Description
Basis light-front quantization is a nonperturbative approach which has been developed for solving many-body bound state problems in quantum field theories. We have applied this approach to investigate the structure of the pion using a light front effective Hamiltonian in the constituent quark-antiquark representation. The remarkable results for the electromagnetic (EM) form factor, distribution amplitudes (DAs), Parton distribution functions (PDFs), pion to photons transition form factor, etc. confirm the robust character of this novel approach. We also investigate several aspects of the nucleon properties such as EM and axial form factors, PDFs, generalized Parton distributions (GPDs), etc. using the framework of BLFQ. We consider the light-front wavefunctions obtained by diagonalizing an effective Hamiltonian consisting of the holographic QCD confinement potential, longitudinal confinement, and a one-gluon exchange interaction with fixed coupling.
