Abstract
We have investigated the unpolarized valence quark generalized parton distribution functions (GPDs) and parton distribution functions (PDFs) for heavy spin-0, B- and D-mesons in the light-front quark model (LFQM). PDFs have been extracted from unpolarized f_1(x, k_perp^2) transverse momentum-dependent parton distribution functions (TMDs). We have solved the quark-quark correlation function to have an unpolarized H(x, zeta, t) GPD. The unpolarized GPDs at zero skewness (zeta=0) lead to describing the electromagnetic form factors (EMFFs) (F_M(t)) and gravitational form factors (GFFs) (A_M(t)) of the mesons.
Summary
Presents unpolarized GPDs and PDFs for heavy B and D mesons in LFQM. Extracts EMFFs and GFFs from GPD moments at zero skewness, providing insights into the spatial and gravitational structure of heavy mesons.
