Los Alamos Heavy Ion Program Future Research Goals, FY05 and beyond

•Examine the suppression/enhancement of J/ production in Au-Au collisions from PHENIX Run-4 data relative to scaled yields from p-p and d-Au. Study the rapidity and pT 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/ 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 p-p collisions.

•Measure π, K and heavy flavor production at forward rapidity via their decays to muons.

•Determine the reaction plane in Au-Au and CuCu 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 color-octet and color- singlet models.
