Twist-4 GTMDs of sea quarks at zero skewness in the light-cone quark model
Abstract
We investigate the twist-4 generalized transverse momentum dependent parton distributions (GTMDs) of u̅ and d̅ quarks inside the proton at zero skewness by adopting the overlap representation within the light-cone formalism. Using the light-cone wave functions of the proton derived from the baryon-meson fluctuation model in terms of the |qq̅B⟩ Fock states, we calculate the twist-4 GTMDs of u̅ and d̅ quarks. Additionally, the intricate relations between the GTMDs and the generalized parton distributions are also explored in our research. Numerical results for these twist-4 GTMDs and twist-4 GPDs at zero skewness are analyzed and presented.
