The parton physics related to correlations of quarks and gluons on  the light-cone can be studied through the matrix elements of pure  spatial correlators in the Bjorken frame. This observation allows  practical calculations of parton properties on a Euclidean lattice.  This includes Feynman parton distributions, generalized parton  distributions, transverse-momentum-dependent distributions, as well as  more generally, light-cone wave functions. It also allows one to  understand the physics of gluon polarization in a polarized proton.
