•Nuclei: From Structure to Exploding Stars
•In Search of the New Standard Model




    Our group has had significant input
     in community planning for future
                activities
    Scientific Themes that Guide our Group
   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 anticipated at the LHC

   Confronting QCD at a fundamental level
      Determine the role of quarks, antiquarks & gluons to the internal
       structure and properties of hadrons
      Understand the origin of hadron spin
        • Quark and gluon spin and orbital angular momentum
          contributions
