Transverse structure of electron in momentum space in basis light-front quantization

Understand

We investigate the leading-twist transverse momentum-dependent distribution functions (TMDs) for a physical electron, a spin-1/2 composite system consisting of a bare electron and a photon, using the Basis Light-front Quantization (BLFQ) framework.

• The light-front wave functions of the physical electron are obtained from the eigenvectors of the light-front QED Hamiltonian.
• We evaluate the TMDs using the overlaps of the light-front wave functions.
• The BLFQ results are found to be in excellent agreement with those TMDs calculated using lowest-order perturbation theory.
