Guidance from the Nuclear Physics Long Range Plan – Dec Our group has had significant input in community planning for future activities QCD and the Structure of Hadrons Phases of Nuclear Matter Nuclei: From Structure to Exploding Stars In Search of the New Standard Model 6

Scientific Themes that Guide our Group l Fundamental Symmetries  Establish standard model parameters of particle physics  Test sensitively for physics beyond the SM These efforts play an important complementary role to the direct discoveries at the LHC l Confronting QCD at a fundamental level  Determine the role of quarks, antiquarks & gluons to the internal structure and properties of hadrons including nuclear effects  Understand the origin of hadron spin s Quark and gluon spin and orbital angular momentum contributions  Hot QCD Size dependence of quark-gluon fluid Jet quenching and structure 7

8 Our Program: QCD l Recently completed experiments  JLab transversity, neutron polarizability, HERMES, Belle, “E866” l Ongoing experiments  PHENIX: recently completed W physics run—antiquark spin  SeaQuest/E906: proof of principle, start production—sea dist’n  COMPASS: commissioning incl. “DC5” wire chamber—TMD l Future  SeaQuest  COMPASS  Heavy Ion/pA collisions at (s)PHENIX and ATLAS—QGP size dependence, jet quenching
