3. J. Hewett Congressional Language – HEP Intensity Frontier: “... the United States has unique capabilities that should be exploited to develop a world-leading program of neutrino science…The Committee directs the Office of Science to submit a report not later than 180 days of enactment that lays out —the expected benefits of intensity frontier science, —a strategy for maintaining the U.S. lead, and —the funding needs over the next 10 years, including construction activities, of implementing the proposed strategy. The Intensity Frontier workshop report should:  Answer the first element of this charge and part of the second  Illuminate the important connections between the 3 Frontiers  Discuss the international context and the role of a strong domestic program in that context 3

11. J. Hewett What is the Intensity Frontier? The Intensity Frontier addresses fundamental questions: Are there new sources of CPV? Is there CPV in the leptonic sector? Are ν’s Majorana or Dirac? Do the forces unify? Is there a weakly coupled Hidden Sector linked to Dark Matter? Are apparent symmetries (B,L) violated at high scales? What is the flavor sector of LHC discoveries? Can we expand the new physics reach of the LHC?

26. J. Hewett What Next? This workshop is just a step in the process towards making this program a reality –See Jim’s talk Broad Intensity Frontier discussion must continue –Centered on science opportunities –Community must speak with one voice –Community must be educated –Working groups should continue in some form - perhaps DPF could take this on

27. J. Hewett What Next? Proponents must engage, and make their case to, the community! Otherwise, you may not like the resulting priorities Arkani-Hamed
