- A. Signori et al.,  "Investigation into the flavor dependence of partonic transverse momentum"
JHEP 11 (2013) 194, arXiv:1309.3507
First exploration about whether different flavour quarks have different intrinsic transverse momentum distributions. The fit is based on SIDIS data obtained by Hermes collaboration (DESY).

JHEP 08  (2024) 232, arXiv:2405.13833
This is the most recent paper, where they extract the intrinsic transverse momentum distributions from a global fit of ~2000 data of SIDIS and Drell-Yan.
