Guidance from the Nuclear Physics Long Range Plan – Dec. 2007

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

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

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

Quark and gluon spin and orbital angular momentum contributions Hot QCD

• Size dependence of quark-gluon fluid• Jet quenching and structure

Management Plan – no major changes

Major issues involve whole group; monthly meetings

Evaluation of current and future research directions

Hiring postdocs, grant issues, tech time requests (bi-weekly)

Each project runs its own budget Equipment, travel, supplies allocated annually in accordance with approved

proposal

Travel, purchases over $250 approved individually by PI
