1 Scoping Study Proposal: Physics Section Introduced by: Paul Harrison University of Warwick

2 Primary Goal “To establish the physics case for (or against!) a neutrino factory in the context of: The likely knowledge of neutrino physics parameters from other anticipated experimental developments between now and the time-frame The possibility of alternative or complementary neutrino beam sources: –next-generation neutrino super-beams –beta-beams”

3 The Physics Case Must be built on the capacity for a NF (and/or alternatives) to answer the outstanding questions: What is the value of |U e3 |? Is there CP violation in neutrino oscillations, and, if so, what is the value of the CP- violating phase,  ? How exact is  symmetry, ie. what is the value of  23 -  /4? Is the mass hierarchy normal or inverted? ie.what is the sign of  m 2 23 ?

4 With Respect to the Above: In context of the other information available in the cited time-frame: What optimised sensitivities on the answers to the above questions might be achieved at a NF? What sensitivities are needed? What sensitivities could be obtained if all/some of the resource were spent, instead, on alternative neutrino oscillation facilities?

5 Proposal Establish of a (set of) Physics Working Groups to answer above questions WG(s) will be comprised of the interested physicists from around the world, working in collaboration. Each will have a convener (or conveners) to coordinate their activities. Activities will be stimulated by a series of Physics Workshops at 3-monthly intervals Output from WG(s) will be chapters, or addenda, to the scoping-study report, which will summarise their activities and report the conclusions.

6 Possible Working Group Topics (for discussion): Appearance measurements Disappearance measurements Overall determination of the MNS matrix elements Beyond SM tests Non-oscillation physics Each WG would consider a neutrino factory, 2 nd -generation superbeams and beta beams. Is this the right way to divide things up?

7 Funding Success relies on funding for travel to the Physics Workshops Workshops will typically last 3-4 days. Typical cost might be 1000 Euros per participant per Workshop. We need to consider this (from where will it be funded?)

8 Conclusion There is no conclusion, as all the above needs to be discussed!
