10. Los Alamos Heavy Ion Program Future Research Goals, FY05 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 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/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 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.

11. Silicon Tracker Upgrade 80 cm 16 cm Current Design Concept Physics extension of the present Muon Arms by clearly identifying the heavy quarks Enhance the single muon effort by identifying decay hadrons on event by event basis

12. Silicon Tracker Upgrade Responsibilities • Mechanical Structure Coordination – Barrel and Endcap • Integrated approach extremely important • LANL has experience, E789, L3, SSC/GEM, MVD • Past relationship with experienced engineering team • PHX chip coordination – Endcap • Collaboration with FNAL (Ray Yarema) to modify existing FPIX2 chip • VTX Engineering Integration
