1. Philip Burrows HEP Forum, Coseners House, 6/05/06 Elementary Particle Physics in the 21 st Century Philip Burrows John Adams Institute Oxford University Report of U.S. EPP2010 Panel

2. Philip Burrows HEP Forum, Coseners House, 6/05/06 What has changed since 1998? Most recent survey of Elementary Particle Physics was completed in 1998 Since then, much has changed –Discovery of Dark Energy  Connections with Astronomy –Discovery of Neutrino Mass  Connections with Nuclear Physics –Precision Electroweak Measurements  World consensus on Linear Collider

3. Philip Burrows HEP Forum, Coseners House, 6/05/06 EPP2010 Charge Committee is charged to: –Identify, articulate, and prioritize the scientific questions and opportunities that define elementary particle physics –Recommend a 15-year implementation plan with realistic, ordered priorities to realize these opportunities Emphasis on evaluating science opportunities –From that, a ranking of the facilities will flow  Linear collider? Neutrino physics? Cosmology?

5. Philip Burrows HEP Forum, Coseners House, 6/05/06 Not your ‘usual Committee’! Non-physicists –Emphasize connections to society at large –Sharpen physics questions Non-particle-physicists –Help engage other scientific communities International representation –Place U.S. particle physics in an international context Overall goal: To present a compelling vision for the field and to create an action plan that will allow it to achieve its goals

6. Philip Burrows HEP Forum, Coseners House, 6/05/06 The Recommendations The US should remain globally competitive in HEP and play a leading role in the worldwide effort: 1) fully exploit opportunities at LHC 2) world-leading centre for ILC R&D + mount a compelling bid to build ILC in the US 3) expand particle astrophysics programme + collaborate internationally on neutrinos

7. Philip Burrows HEP Forum, Coseners House, 6/05/06 The ILC (1) The US should launch a major program of R&D, design, industrialisation, management, and financing studies for accelerator and detectors 1) $300-500M over next 5 years on accelerator 2) $20-30M / year for detectors for 6-10 years (did not address detailed cost estimates for ILC)

8. Philip Burrows HEP Forum, Coseners House, 6/05/06 The ILC (2) The US should announce its strong intent to become the host for the ILC Should undertake necessary work to provide a viable site (FNAL) and mount a compelling bid Only the ILC will allow the US to maintain, in the long term, a world-leading, internationally collaborative, programme in HEP

9. Philip Burrows HEP Forum, Coseners House, 6/05/06 Neutrinos US should participate in a well-coordinated, staged, internationally planned programme Nature of neutrino mass (double beta decay) International study of accelerator-based experiments should determine a sensible plan Longer-term: CP violation (proton decay)
