  1. Beyondq13 Gabriela Barenboim APS Neutrino Study: Reactor Working Group

  2. We have just closed annus mirabilis • K2K: “Indication of neutrino oscillations in a 250 km …” • “First Results from KamLAND: Evidence for Reactor …” • Nobel Prize award to R. Davis Jr. and M. Koshiba • WMAP: First year Wilkinson microwave anysotropy probe observations: determination of cosmological parameters • “Precise measurements of the solar neutrino D/N and seasonal variations in Super-Kamiokande” • SNO salt phase results: “Measurements of the Total…” • Sloan Digital Sky Survey: “Cosmological parameters…”

  3. It is indeed a gift

  4. Let's not blow it !!

  5. The evidence

  6. We obtained Dm223 = (1.3 – 3.0) 10-3eV2 sin2 (2 q23) > .9 atmospheric Dm212 = (5.8 – 8.4) 10-5 eV2 tan2 (q12) < .52 solar

  7. The next step • the mass hierarchy • the connecting angle q13 • the CP violating phase d

  8. Is there any physics beyond q13 ?

  9. Yes !!!!

  10. Yes !!!! Measure or bound neutrino magnetic moment

  11. Yes !!!! Measure or bound neutrino magnetic moment Search for oscillation effects of sterile neutrinos

  12. Yes !!!! Measure or bound neutrino magnetic moment Search for oscillation effects of sterile neutrinos Measure sin2 qw (check NuTeV result)

  13. Yes !!!! Measure or bound neutrino magnetic moment Search for oscillation effects of sterile neutrinos Measure sin2 qw (check NuTeV result) FINeSE at a reactor ?

  14. Yes !!!! Measure or bound neutrino magnetic moment Search for oscillation effects of sterile neutrinos Measure sin2 qw (check NuTeV result) FINeSE at a reactor ? Anything interesting about structure functions ?

  15. Yes !!!! Measure or bound neutrino magnetic moment Search for oscillation effects of sterile neutrinos Measure sin2 qw (check NuTeV result) FINeSE at a reactor ? Anything interesting about structure functions ? What about supernovas ?

  16. Yes !!!! Measure or bound neutrino magnetic moment Search for oscillation effects of sterile neutrinos Measure sin2 qw (check NuTeV result) FINeSE at a reactor ? Anything interesting about structure functions ? What about supernovas ? CPT tests (reactor vs solar neutrinos)

  17. WE KNOW "FOR SURE" THAT CPT IS VIOLATED IN NATURE !!!

  18. WE KNOW "FOR SURE" THAT CPT IS VIOLATED IN NATURE !!! We have measured a cosmological constant that is different from zero

  19. Beware of CPT !

  20. To keep in mind • Low Homestake rate ? • Absence of the upturn of the spectrum ?

  21. SNO Spectrum ? Turn down at low energies ?

  22. To keep in mind • Low Homestake rate ? • Absence of the upturn of the spectrum ? Next KamLAND data release: still some shift in Dm2 is not excluded….

  23. There is a rich non-q13 program which might help make the q13 program happen.

  24. Measure or bound neutrino magnetic moment • Search for oscillation effects of sterile neutrinos • Measure sin2 qw (check NuTeV result) • FINeSE at a reactor ? • Anything interesting about structure functions ? • What about supernovas ? • CPT tests (reactor vs solar neutrinos)

  25. Let's not sit on it !
