We use up to 7.3 fb-1 of ppbar collisions collected with the D0 detector study different differential distributions for Z/gamma* produced in ppbar collisions at the Tevatron collider. In one study we investigate the transverse momentum distribution of the Z/gamma* boson by using a novel observable that has reduced sensitivity to the effects of experimental resolution and efficiency, allowing detailed investigations of QCD predictions for the dependence of the Z boson transverse momentum on its rapidity. In a second study we investigate the angular distribution of the Z/gamma* decay products as a function of their invariant mass and derive measurements of the electroweak mixing angle and of the Z-light quark couplings.
