Generalized parton distributions of gluon in proton: a light-front quantization approach

Understand

We solve for the gluon generalized parton distributions (GPDs) inside the proton, focusing specifically on leading twist chiral-even GPDs.

• We obtain and employ the light-front wavefunctions (LFWFs) of the proton from a light-front quantized Hamiltonian with Quantum Chromodynamics input using basis light-front quantization (BLFQ).
• Our investigation incorporates the valence Fock sector with three constituent quarks and an additional Fock sector, encompassing three quarks and a dynamical gluon.
• We examine the GPDs within impact parameter space and evaluate the $x$-dependence of the transverse square radius.
