摘要 We obtain the leading-twist valence quark transverse-momentum-dependent parton distribution functions(TMD PDFs)of quarks in the proton within the basis light-front quantization(BLFQ)framework.Our results are consistent with lattice QCD calculations and the previous BLFQ calculations of the collinear dirtibutions.We also obtain consistency with the So er-type bounds.Within our approach,we nd that six T-even TMDs in the leading twist are all independent of each other,and previously found model-dependent relations do not hold.This is a promising sign that our results are representative of future,more extensive treatments of QCD(Fig.1).
