Extraction of the first transverse moments of Sivers and $g^{\perp}_{1T}$ PDFs from COMPASS SIDIS data
According to QCD the quark structure of the nucleon spin within the $\textit{twist-2}$ approximation is parameterized by eight transverse-momentum-dependent (TMD) parton distribution functions (PDFs). The PDFs describe the distributions of longitudinal and transverse momenta of partons and their c...
