  1. Recent Cold Nuclear Matter results from d+Au collisions New J/ suppression from 2008 d+Au data compared to theory (Colorado, LANL, FSU) arXiv:1010.1246 ,  and  suppression for forward-rapidity d+Au(L. Guo – LANL) STAR (prelim) arXiv:1010.1246 J/ψ impact parameter dependence of suppression not linear with nuclear thickness (Colorado, LANL, FSU)  Upsilon suppression in 2008 d+Audata (Korea U., LANL) Isolating & quantifying gluon saturation & CNM dE/dx LANL - M. Leitch

  2. J/ψ Suppression in Au+Au Collisions Recent attempt to extrapolate and divide out d+Au cold nuclear matter effects & show “anamolus” suppression in A+A from various experiments (Leitch) Plot by Leitch @ Seattle/INT Workshop – June 09 New Au+Au J/ suppression from 2007 compared to various theories (Colorado, LANL) J/ψ versus pT versus centrality PHENIX Internal PHENIX Internal energy density LANL - M. Leitch

  3. Fixing cross-talk problems by terminating anodes in Muon Tracker – Important especially for W measurements in muon arms (LANL, RIKEN, Korea U.) New capacitors that connect anodes to terminators Manlift work on station-1 to put termination on Terminators designed and installed in tight spaces LANL - M. Leitch

  4. Leitch (d+Au), Aidala (spin), van Hecke • replace central arms with solonoid magnet & compact EMCal & HCal • replace South muon arm with very-forward electron-capable spectrometer (2016-2018) LANL - M. Leitch

  5. Physics of the PHENIX Decadal Plan QGP and CNM Physics Spin Physics • Are quarks strongly coupled to the quark-gluon plasma at all interaction distance scales? • What are the detailed mechanisms for parton-QGP interactions and responses? Are the interactions coherent over the entire medium length scale, what are the dominant energy loss mechanisms? • Are there quasi-particles in the medium? What is their mass and width? • Is there a relevant color screening length in the quark-gluon plasma? • How is rapid equilibration and entropy production achieved? • What is the nature of color charge in large nuclei? What role does gluon saturation and the EMC effect play in nucleus-nucleus collisions? How do these modifications evolve? • Dynamical Origins of Spin-Dependent Interactions • New Probes of Longitudinal Spin Effects • Measurements with Polarized He3 and Increased Energies EIC Physics • Inclusive e+p physics to measure polarized and unpolarized structure function and advance knowledge of quark and gluon contributions to proton spin. • Nuclear parton distribution fucntions (nPDFs), relevant to study of gluon saturation effecs. • Elastic diffractive physics to provide tomography of the nucleon and to help define the initial state for heavy-ion collisions LANL - M. Leitch
