Description
A dense hadronic system, such as a heavy nucleus or a hadron boosted to high energies, generates strong gluon fields dominated by their classical component. The high density is described by the saturation momentum scale, which provides a dynamical short-distance cutoff and makes these dense systems amenable to perturbative calculations. Building on our previous work, we calculate the transverse-momentum-dependent (TMD) quark parton distribution functions of a dense, unpolarized spin-1/2 system. The possibility of spin-orbit coupling results in nontrivial mixing between the unpolarized and Boer-Mulders TMD's.
