Description

Using a recently developed light-front spectator model that incorporates gluon, where the light-front wave functions are modeled from the soft-wall anti–de Sitter/QCD prediction, we examine the leading twist gluon generalized parton distributions (GPDs) inside the proton. We derive the chirally even and odd distributions by using the overlap representation of the light-front wave functions. In terms of GPDs at nonzero skewness, we investigate the entire three-dimensional representation of gluons. We analyse the gluon impact parameter distributions at ξ=0 using the Fourier transform of GPDs. We address the total angular momentum contribution of the gluons by using the Ji's sum rule and also give our predictions for both the canonical and kinetic orbital angular momentum in the light-cone gauge.
