Description
Studying the role of gluons in exclusive scattering processes is essential as new physics programs, such as an electron ion collider, are planned in unprecedented kinematic regimes. We present a parameterization of gluon generalized parton distributions (GPDs) calculated using a reggeized spectator model. This parameterization is constrained using a combination of lattice QCD form factor calculations and extracted deep inelastic parton distributions. We evolve our parameterization at leading order in $Q^2$ to the scale of experimental data using a perturbative QCD evolution framework. Through Fourier transform of the transverse momentum transfer $\Delta_{T}$, we can develop images of the transverse spatial distribution of the gluons. Understanding the behavior of gluon GPDs is a first step towards extracting the gluon contribution to deeply virtual Compton scattering (DVCS) and timelike Compton scattering (TCS) observables.
