Goal is to Explore the Fundamental Interactions of Energy, Matter, Time,

and Space

  • Understand the unification of fundamental particles and forces and the mysterious forms of unseen energy and matter that dominate the universe
  • Search for possible new dimensions of space

 Connections between the physics of

elementary particles and the physics that

determines the structure of the universe

HEP Office supports ~ 90% of U.S. High

Energy Physics and coordinates with NSF,

NASA and international efforts

We coordinate our program with the

National Science Foundation (NSF),

the scientific context discovery
The Scientific Context - Discovery

Plans for FY 2007  R&D Investment in Future Initiatives:

      • International Linear Collider
      • new neutrino experiments – accelerator & reactor
      • long-term accelerator technologies
      • Dark Energy - Increase R&D for ground- and space-based concepts
  • We are entering the age of the Terascale energies
    • The reigning theory (Standard Model) is as precise as it is incomplete.
    • How the weak and electromagnetic forces unify is a mystery …but the consequences are likely dramatic
  • Dark Energy & Dark Matter (what the … is it?)
  • Neutrinos – what are they and how do they interact?

Draft report release on 4/28/06 –

Recommendations in priority order:

  • Fully exploit the opportunities for U.S. involvement at the Large Hadron Collider (LHC) at CERN
  • Comprehensive program to become the world-leading center for R&D for the International Linear Collider (ILC) and mount a compelling to build it in the U.S.
  • Expand the program in particle astrophysics and pursue an internationally coordinated, staged program in neutrino physics.

Now will show some of our astrophysics and cosmology related efforts & projects 

dark energy planning future
Dark Energy – Planning & Future

 Investigating future space and/or ground telescopes in cooperation with NASA and NSF.

 Dark Energy Projects are being considered by P5 panel.

 Planning how to review and select which project(s) go forward – in view of DETF report

  • Continue to plan a Joint Dark Energy Mission with NASA & we’re open to the possibility of International Collaboration
    • High priority in DOE Strategic Plan
    • DOE/NASA Science Definition Team

Dark Energy R&D:

Doing R&D for SuperNova Acceleration Probe (SNAP) concept for JDEM

Labs doing small amount of R&D for DES (Dark Energy Survey) and LSST (Large-scale Synoptic Survey Telescope)

In FY07 Request, additional R&D of ~$5M available – ground and/or space concepts will be selected by open competition; DETF will guide us

        • funding levels reflect tentative plan which may change based upon advice from DETF and other relevant considerations
