Steering Group Charge

In his remarks to HEPAP, Undersecretary Orbach requested a dialog with the HEP community:

"In making our plans for the future, it is important to be conservative and to learn from our experiences. Even assuming a positive decision to build an ILC, the schedules will almost certainly be lengthier than the optimistic projections. Completing the R&D and engineering design, negotiating an international structure, selecting a site, obtaining firm financial commitments, and building the machine could take us well into the mid-2020s, if not later. Within this context, I would like to re-engage HEPAP in discussion of the future of particle physics. If the ILC were not to turn on until the middle or end of the 2020s, what are the right investment choices to ensure the vitality and continuity of the field during the next two to three decades and to maximize the potential for major discovery during that period?"

Steering Group Charge (cont.)

With the encouragement of the Office of Science and the support of Professor Mel Shochet, the chair of HEPAP, Fermilab will develop a strategic roadmap for the evolution of the accelerator-based HEP program, focusing on facilities at Fermilab that will provide discovery opportunities in the next two to three decades. This roadmap should keep the construction of the ILC as a goal of paramount importance. To guide this proposal, the Fermilab Director has appointed a Steering Group consisting of members from Fermilab and the national particle and accelerator physics community to insure that the plan serves national needs. The Steering Group will also engage additional constituents in the analysis of the various physics opportunities.

Steering Group Charge (cont.)

The Steering Group will build the roadmap based on the recommendations of the EPP2010 National Academy report and the recommendations of the P5 subpanel of HEPAP. The Steering Group should consider the Fermilab based facilities in the context of the global particle physics program. Specifically the group should develop a strategic roadmap that:

1. supports the international R&D and engineering design for as early a start of the ILC as possible and supports the development of Fermilab as a potential host site for the ILC;

2. develops options for an accelerator-based high energy physics program in the event the start of the ILC construction is slower than the technically-limited schedule; and

3. includes the steps necessary to explore higher energy colliders that might follow the ILC or be needed should the results from LHC point toward a higher energy than that planned for the ILC.

Steering Group Charge (cont.)

I am asking Deputy Director Kim to chair the Steering Group.

Any recommendations that might be relevant to the FY09 budget should be transmitted as early as possible.

The Steering Group's final report should be finished and delivered to the Fermilab Director by August 1, 2007. This deadline would allow for presentations to the DOE and its advisory bodies before the structuring of the FY2010 budget.

US HEP Physics Priorities:

• EPP2010 and P5 have addressed US HEP priorities.

• Both stressed the importance of a diverse program– Priority doesn’t mean you only do items at the top of the list

• Both EPP2010 and P5 assumed– a fast decision on ILC construction (2010)– a technically driven schedule for ILC construction

EPP2010 Priorities (in order)

• The energy frontier– LHC (including upgrades)– ILC: Emphasis on US bid to host

• The particle/astro connection– Emphasis on dark matter/dark energy

• Neutrinos– Focus was on a global program

• Flavor physics

P5 Recommendations

• 60% of new investments to ILC R&D• 40% to smaller initiatives

– Attempt to quantify importance of diverse program

– DES– CDMS, 25 kg

– Daya Bay– NOvA

– For the long term, LSST & SNAP development

Steering Group’s Emphasis

• Need for an intermediate physics-driven program

– Will the physics be important when the experiment is done?

– Better at Fermilab than at other labs (e.g. JPARC)?

– Unique in its physics reach? - Will it answer questions not answered at the LHC?

• Alignment with ILC:

– Will this advance the ILC?– Development of an accelerator facility that helps ILC– Compatibility with the ILC Schedule

Steering Group: Physics Opportunities

• Science– Neutrino Physics– Precision measurements involving charged

leptons and quarks

• Needed facilities– Proton Intensity Frontier: intense , , K, p beams– Beta Beam– Collider Luminosity Frontier: Super B, Giga Z, …

Steering Group: Physics Opportunities

• Neutrino: Oscillation, CPV, X-Section, EWK Precision• Muon: Lepton Number Violation

• Kaon: CKM Matrix, Lepton Flavor Violation• Anti-proton: Hyperon CPV, Charm• B Physics• Electroweak Precision with Giga Z• …

Compositeness to 3000 TeV scale

Supersymmetric models predict Rμe~ 10-15 for weak scale SUSY

• “Proton Intensity Frontier” offers rich menu of neutrino, muon, and kaon physics in near - mid term

– Physics driver is search for Beyond the Standard Model Physics

– Window to high energy scales in some scenarios– Physics reach is complementary to energy frontier

• “Beta Beam”– Longer term, No Synergy to ILC

• “Luminosity Frontier”– Large scale, longer term

Preliminary Conclusions on Science

“Proton Intensity Frontier” Option:Reconfiguration of Existing Facilities

• Examples– sNuMI (super NuMI) – ~1.3 MW at 120 GeV

• Modification of Accumulator and Recycler– Debuncher as an 8 GeV Slow Spiller– Tevatron as a 120 GeV Slow Spill Stretcher Ring

• Capable of producing protons with– 120 GeV >1 MW– 8 GeV slow & fast spill– 120 GeV slow spill

• Alignment with ILC– No synergy– But modest cost for construction– Operations - the current 30+ year old complex
