Nucleon partonic spin structure to be explored by the unpolarized Drell-Yan program of COMPASS experiment at CERN
The observation of the violation of Lam-Tung relation in the $\pi N$ Drell-Yan process triggered many theoretical speculations. The TMD Boer-Mulders functions characterizing the correlation of transverse momentum and transverse spin for partons in unpolarized hadrons could nicely account for the vio...
