  2. Preface: “Long-Baseline” Definition • Dictionary definition of long - “having considerable linear extent in space” • Longer than before / Off the site of the accelerator • Beam -- L >> length of beam pipe YES Which implies the far detector sees a point source of neutrinos • Physics – L >> pE/(2.54 Dm322 ) ~ 1500kmNO Maury Goodman, ANL NOW 2008 September 2008

  3. Preface:[Factors in North America/US] • National Planning in the US is done by a panel called HEPAP (High Energy Physics Advisory Panel) • Long-Term Planning is done every few years by subpanels • A recent innovation is to have a panel called P5 (Particle Physics Project Prioritization Panel) maintain a roadmap. • The highest priority project in a 2001 report was the ILC (Bagger-Barish Panel) • The ILC Central Design Group Reference Design Report reported an ILC cost in August 2007. The advertised cost was $6.6B. The estimated US project cost is $21.9B. [These are the same number!] • Too much ->-> Therefore new study Maury Goodman, ANL NOW 2008 September 2008

  5. Outline • MINOS a few results • MINOS+ speculation & opinions • NOnA • LB DUSEL • Water • Liquid Argon Thanks to M. Sanchez, H. Gallagher, G. Feldman, M. Diwan, N. Saoulidou, M. Messier, M. Bishai, G. Rameika, R. Svoboda, Y.K. Kim, K. Lesko, B. Fleming, L. Pinella, Maury Goodman, ANL NOW 2008 September 2008

  6. Plusmore baselines… • To have some more facts in this talk, I’ll mention several things having to do with baseball*. • Fully realizing a large fraction of my audience doesn’t care in the least about baseball Maury Goodman, ANL NOW 2008 September 2008

  7. MINOS • 484 planes of 4cm strips SEE DETAILS FROM JUSTIN EVANS THIS AFTERNOON Maury Goodman, ANL NOW 2008 September 2008

  8. NuMI Beam Performance 12 May 2008 Total Protons (E20) Maury Goodman, ANL NOW 2008 September 2008 8

  9. MINOS - Dm232Energy Spectrum • |m2| =(2.43±0.13) x 10-3 eV2 • (68% C.L.) Events / GeV • Best Fit: • |m2|= 2.43x10-3 eV2 • sin2(2) =1.00 Maury Goodman, ANL NOW 2008 September 2008 9

  10. NC Atmospheric ns Alternative fits to oscillations Time of flight Search for Lorentz Violation Cosmic m+/m- Cosmic shadows, seasonal variations,… ne for q13 Antineutinos for Dm232 MINOSOther Analyses Maury Goodman, ANL NOW 2008 September 2008

  11. Cosmic RaysCharge Ratio • Previously m+/m- flat • First rise in Charge Ratio m+/m- • Relevant variable is not Em by Emcosq • Can be used to measure K+/K- & p+/p- • Related to TeV associated production • Relevant for Neutrino Telescope backgrounds (n/n) Maury Goodman, ANL NOW 2008 September 2008

  12. ne Sensitivity for q13 • At CHOOZ limit expect 12 νe signal events and 42 background events with 3.25x1020 protons. • Use sidebands to study predicted far detector backgrounds. Maury Goodman, ANL NOW 2008 September 2008

  13. MINOS plans • Running on FNAL schedule through 2010 • ~10e20 pot • We want to continue running ns beyond 2010 • We want to run ns • A “scenarios” group is devising a plan/proposal • Running beyond 2010 seems obvious, but you never know. Maury Goodman, ANL NOW 2008 September 2008

  14. Baseball • They play almost every day (162-182/year) • Many fans appreciate statistics • You can understand about 70% of the game in 30 minutes • Much that remains is fairly subtle • Huge influence - metaphors on English language (MVP, double play, off base, hit it out of the park, pinch hitter, foul ball, all-star, big league, rain check, …) • Most common questions when I take a European to a baseball game (~40,000) • Why are there no policeman? • What is light beer? Maury Goodman, ANL NOW 2008 September 2008

  15. NOnA-Where? Off-axis The Ash River site is the furthest available site from Fermilab along the NuMI beamline. This maximizes NOnA’s sensitivity to the mass ordering. Maury Goodman, ANL NOW 2008 September 2008

  16. NOnA designplastic filled with scintillator 32-cell extrusions. The planes alternate horizontal and vertical. An admirer Maury Goodman, ANL NOW 2008 September 2008

  17. NOnAA significant Issue • It takes a long time to build & fill • It is desirable to take data before it is complete • Gluing & Structural Engineering challenges “The problem with plastic is that it is plastic” Maury Goodman, ANL NOW 2008 September 2008

  18. Signal & Background x-z y-z Maury Goodman, ANL NOW 2008 September 2008

  19. NOnA – nonzero q13 ? Maury Goodman, ANL NOW 2008 September 2008

  20. NOnA – mass hierarchy ? Maury Goodman, ANL NOW 2008 September 2008

  21. NOnA – CP ? Maury Goodman, ANL NOW 2008 September 2008

  22. NOnA oscillations • NOnA was approved at Fermilab and construction funds were included in the DOE 07-08 proposed budget ($12M first year of $260M) • Funds also in Congressional budgets, but retroactively zero’d in a December 07 compromise • P5 report recommended NOnA, but not in all funding scenarios. • A supplemental funding bill in July 08 included $9.2 M for NOnA • It recently passed its (second) CD2 review – not yet signed. • Hardware & Civil projects that had been delayed are gearing back up. Maury Goodman, ANL NOW 2008 September 2008

  23. Haven’t won “World Series” since 1908 1630 teams Cubs 4 wins -0 losses on days that Italy has won the world cup 2008- This is the year Chicago Cubs Maury Goodman, ANL NOW 2008 September 2008

  31. Long-Baseline

  32. 3 100kt detectors? Maury Goodman, ANL NOW 2008 September 2008

  33. LB-DUSELA significant Issue • It will take a long time to build & fill • It will be desirable to take data before it is complete  One of the arguments for Modular H2O Maury Goodman, ANL NOW 2008 September 2008

  34. Maury Goodman, ANL NOW 2008 September 2008

  35. Water or Liquid Argon? Maury Goodman, ANL NOW 2008 September 2008

  36. Maury Goodman, ANL NOW 2008 September 2008

  37. On-Axis or Off-Axis? • On-Axis More flux • Off-Axis Less Background • Design a Flexible Beam? Maury Goodman, ANL NOW 2008 September 2008

  38. Maury Goodman, ANL NOW 2008 September 2008

  39. One (unofficial) notion of a LB-DUSEL schedule Maury Goodman, ANL NOW 2008 September 2008

  40. DUSEL long-baselineis a vision • The vision requires: (all cost figures MCG rumor quality) • DUSEL ($500M+) • A new beamline at Fermilab ($250M) • Project X ($1B) • A new huge detector ($500M-1B) None of these currently exist or are “approved” • It is not clear that this fits the funding assumptions of P5, or that it is a community consensus. Maury Goodman, ANL NOW 2008 September 2008

  41. Other ideas • 5 kt Ar at Soudan • Use Brookhaven’s AGS • Detector at 2nd maximum in NuMI beam • Neutrino Factory/Muon Collider Maury Goodman, ANL NOW 2008 September 2008

  42. NOW 2020Intercontinental Long-Baseline JPARC-INO FNAL-INO CERN-INO ETC… Maury Goodman, ANL NOW 2008 September 2008

  44. Conclusions • MINOS is taking data • Results at 4e20, Dm232 • Expected ~ 10e20, q13 • NOnA is coming • LB-DUSEL may be next • With regard to planning, (in my humble opinion) we are overdue for an effective international context • Neutrino fans are in for exciting times • Chicago Cubs fans are looking forward to the 2008 baseball World Series Maury Goodman, ANL NOW 2008 September 2008
