One of the most important questions in nuclear physics is the role of color gauge invariance. The so-called "Sivers" distribution function presents an ideal testing ground for measuring the consequences of this invariance, as the function depends non-trivially on the color. A new paper finds that the Sivers function exhibits process dependence by comparing semi-inclusive deep-inelastic scattering data with proton-proton jet asymmetries. JLab measuremets at 12 GeV in the region of large momentum fraction x will be crucial for further confirmation of this finding.
