D(p)+Au+X measurement of the

A d(p)+Au+X measurement of the parton model gluon density distributions xg(x) in gold nuclei for 0.001< x <0.1. For 0.01<x<0.1, this measurement tests the universality of the gluon distribution.

• A d(p)+Au+X measurement of the parton model gluon density distributions xg(x) in gold nuclei for 0.001< x <0.1. For 0.01<x<0.1, this measurement tests the universality of the gluon distribution.

• Characterization of correlated pion cross sections as a function of Q2 (pT2) to search for the onset of gluon saturation effects associated with macroscopic gluon fields. (again d-Au)

• Measurements with transversely polarized protons that are expected to resolve the origin of the large transverse spin asymmetries in reactions for forward  production. (polarized pp)
