摘要：

Three measurements that broaden the scope of the experimental investigation of quarkonia modifications in heavy ion collisions are presented. Although the current statistical precision on the first two measurements does not allow one to draw significant conclusions, J/psi elliptic flow and high p(T), suppression results are important proofs of principle measurements, and make the case for higher luminosities at RHIC. Finally, the first measurement of an upper limit on the nuclear modification R-AA of dielectrons in the (sic) mass region in Au+Au collisions is presented. The results show a significant suppression with an upper limit of <0.64 at 90% CL.
