Description
The structure of $\rho$-meson is investigated through the leading-twist momentum-dependent parton distribution functions within the basis light-front quantized (BLFQ) framework. To begin with, the light-front wavefunctions (LFWFs) are computed by truncating the light-front Hamiltonian to take into account the valence Fock sector and the one containing a dynamical gluon, $|q\bar{q}\rangle$ and $|q \bar{q} g\rangle$. Then, these wave functions are employed to study the so-called parton distribution functions (PDFs), which are the one-dimensional functions, in addition to the three-dimensional transverse momentum-dependent parton distribution functions (TMDs). Comparing our predictions with other model results confirm a qualitative consistency for the valence quark PDFs and TMDs. We, further, show some gluon distributions in which $\rho$-meson does not transfer orbital angular momentum from initial to its final state, that make us investigate the distributions $f^g_1, g^g_{1L}, h^g_1$ and $f^g_{1LL}$ in momentum space.
