    1. Fermilab and Planning the Future of U.S. High Energy Physics Robin Staffin United States Department of Energy April 2005

    2. Fermilab and High Energy Physics • The purpose of my talk is to discuss the DOE view towards the future of high energy physics in the US and Fermilab’s role in it. • Fermilab is a GREAT LABORATORY, that has played a central and critical role in US particle physics. • The laboratory is approximately 40% of the National DOE HEP budget. This is up almost 5% from the late-90s.

    3. Fermilab and High Energy Physics(cont’d) • But I’m here to talk about the future. • Simply put, Fermilab will play a central and critical role for US particle physics – both here and abroad. • We know that budgets have been very stressful – in carrying out our existing programs with the universities, and planning for our future. • But we’re in this together, as partners. I need your help in making a successful US program and a successful Fermilab for our future. The two are inextricably linked.

    4. What this requires • A clear and compelling message from the laboratory community • What science should we pursue and why it’s the most exciting thing in the universe • What tools are necessary to advance this great adventure • NOT an alphabet soup of facilities • NOT a facility in every pot • NEED a simple unifying science case. • The tools (facilities) should follow from the science • While intensive discussion is good – even necessary – in determining the best scientific program, incessant bickering can be damaging to our health. • Don’t kid yourselves. The outside world hears about the bickering.

    5. The DOE HEP program in FY 2006 • Overall HEP budget and priorities in FY 2006: • Tevatron and B-factory will be fully supported • LHC preparations will be fully supported • Core research program at the universities and laboratories will be maintained • Investment for near and long term new initiatives (including neutrinos and ILC R&D) will be increased • Any new initiatives will have to come from re-direction

    6. DOE Office of ScienceFY 2006 Congressional Budget Request • FY 2006 Request is 3.9% below FY 2005 Appropriation • The budget forces us to make tough choices. • No new starts in FY 2006 • Prioritizing ongoing programs ($M)

    7. Office of Science Planning Profile 3.60 3.46 3.39 3.39 3.39 3.34 $127M (~3.7%) decrease over 5 years

    8. The World HEP Program Over the next decade the world program will become increasingly focused on • The Energy Frontier • Discover and then explore a world of TeV scale new physics • Tevatron  LHC  ILC • The “other 95% of the universe” • Dark matter • direct detection; production at accelerators? • Dark energy • how to learn more? • Neutrinos • Neutrinos are different: what is this telling us? • Masses – do not come from Higgs? • Majorana nature – neutrino-antineutrino mixing? • CP violation – origin of matter?

    9. Intermediate scale projects • The current U.S. accelerator-based program is world-leading, but finite in lifetime • PEP-II and the Tevatron will ramp down toward the end of the decade; miniBooNE, MINOS also • The Linear Collider is DOE’s highest priority for a future major facility • but timescale is uncertain and cannot be done without either an increase in resources or a reduction in cost • LHC participation will be a central piece of the U.S. program Hence DOE has started planning for a portfolio of medium scale, medium term experiments to be launched in the period 2007-10 • Scientific opportunities are compelling • neutrino physics (APS study); dark matter, dark energy… • Resources will become available, through redirection

    12. APS neutrino study recommended Now Next decade Upgrade beamline And/Or New detector(s) And/Or Muon storage ring as neutrino factory New Reactor experiment Measure 13 Decision pointhow big is 13? New Accelerator experiment “off axis” Measure 13 and mass pattern CP violation? New Double beta decayexperiment Probe mass and Majorana nature

    13. New Initiatives • In order to inform the Department of our intent to pursue several new scientific topics, we plan to prepare draft requests for approval of “CD-0” (Statement of Mission Need), including • A generic reactor-based neutrino experiment to measure 13 • A generic off-axis accelerator-based neutrino experiment for 13 and to resolve the neutrino mass hierarchy • A generic high intensity neutrino beam facility for neutrino CP-violation experiments • A generic neutrinoless double-beta decay experiment to probe the Majorana nature of neutrinos • A generic underground experiment to search for direct evidence of dark matter • A generic ground-based dark energy experiment • In order to be ready to move forward expeditiously, this will be done in parallel with an advisory process selecting the best options

    15. ILC and 21st century physics • Have we really discovered the Higgs • Is it a scalar particle? • Does it couple to mass? • Have we really discovered supersymmetry? • Same coupling, different spin? • Have we really discovered dark matter? • Does it have the right properties?

    16. Conclusion:Three big goals for us all • Make ongoing program (Tevatron, NuMI/MINOS, LHC etc) a success • Develop and make real a coherent program of experiments in dark matter, dark energy and neutrinos • Redirection will allow some significant investments • Fermilab infrastructure is a good basis for a phased, extensible accelerator based neutrino program with international involvement • Synergies with linear collider work • Capture the momentum of LHC discoveries and then use it to build a broad consensus to launch the ILC

    17. What next for Fermilab? • We look forward to working with Fermilab to develop a strong future for the laboratory as well as for the overall high energy physics program. • The laboratory’s own Long Range Plan laid out a broad and exciting program for the next decade, centered on the International Linear Collider, significant new initiatives in neutrino physics, the LHC physics center, and particle astrophysics and underground experiments. • We are committed to maintaining Fermilab as one of the world’s leading scientific facilities.
