Transverse momentum structure of proton within the basis light-front quantization framework

Understand

We obtain the leading-twist valence quark transverse-momentum-dependent parton distribution functions (TMD PDFs) for the proton within the basis light-front quantization (BLFQ) framework.

• Our results are consistent with lattice QCD calculations and our previous results for the collinear limit.
• We also obtain consistency with the Soffer-type bounds.
• Within our approach, we find that six T-even TMDs in the leading twist are all independent of each other, and previously found model-dependent relations do not hold.
