UNCLASSIFIED Los Alamos Heavy Ion Program Future Research Goals, FY 05 and beyond • Examine the suppression/enhancement of J/y production in Au-Au collisions from PHENIX Run-4 data relative to scaled yields from p-p and d-Au. Study the rapidity and p. T dependence to determine whether or not a quark gluon plasma is formed. • Extract open charm production in Au-Au collisions via single muon, dimuon, and possibly electron-muon channels to help disentangle J/y suppression due to the QGP and small x physics from nuclear medium effects. • Study gluon shadowing, parton energy loss and the Cronin effect in d-A and pp collisions. • Measure π, K and heavy flavor production at forward rapidity via their decays to muons. • Determine the reaction plane in Au-Au and Cu. Cu collisions at forward rapidities using the endcaps of the MVD. • Perform R+D for a silicon vertex detector upgrade. Begin design and construction of the detector mechanical structure and a silicon Endcap detector. • Calculate theoretical open charm production cross sections using the coloroctet and color- singlet models.
