Transverse momentum distributions of valence quark in light and heavy vector mesons

Understand

We study the leading-twist time-reversal even transverse momentum dependent parton distribution functions (TMDs) of light and heavy vector mesons, i.e., the $\rho$, $J/\psi$ and $\Upsilon$.

• We employ the leading Fock-state light front wave functions (LF-LFWFs) of $\rho$ and $J/\psi$ from our recent study, and supplement with $\Upsilon$'s LF-LFWFs.
• These LF-LFWFs are extracted from dynamically solved Bethe-Salpeter wave functions.
• The vector meson TMDs are then studied with the light front overlap representation at leading Fock-state.
