  The large mass of the charm quark, along with the abundance of J/psi mesons
observed from proton-proton collisions at PHENIX, allow for new measurements
which are sensitive to basic properties of QCD. Two measurements are presented
in this document: a transverse single-spin asymmetry (SSA) of J/psi production
and the angular distribution for decay leptons in various reference frames. The
decay distribution is directly sensitive to the J/psi production mechanism,
while the transverse SSA is also sensitive to the distribution of gluons in a
transversely polarized proton. Taken together, the two measurements provide a
wealth of information about the formation of a J/psi meson.
