DAE HEP 2024 contribution on pion valence quark structure using light-front dynamics, highlighting S-wave dominance and Mellin moment predictions.
The question
In this work, we investigate the leading twist valence quark distribution functions of pion using the light cone quark model (LCQM). We calculate the time reversal f_1(x, k_perp^2) quark transverse momentum parton distribution functions (TMDs) using the S-wave and P-wave meson state along with the parton distribution functions (PDFs). It is found that the S-wave contributes 94% to the TMDs and PDFs of pion, while P-wave contributes only 6%. We also calculate the average transverse momentum, Mellin moment and inverse moment for valence quark of pion.
What we found
Calculates pion valence quark TMDs and PDFs using S-wave and P-wave states in LCQM. Finds S-wave contributes 94% while P-wave contributes only 6%, and computes Mellin and inverse moments for the valence quark.
